Optimize shifts that are known to be right shifts.
Without this, the general shift vop is used which has to test for the
sign of the shift before shifting. This micro-optimization removes
the test when we know the sign of the shift.

Make the version arg optional.
If the version is not specified, determine a default version based on
the git hash returned by git describe. Thus, for tagged snapshot
builds, the version will automatically be chosen from the tag, with
"snapshot-" removed.

+
+Unix syntax is used whether or not the underlying system is Unix;
+on such non-Unix systems it is only usable but for relative pathnames;
+but especially to manipulate relative pathnames portably, it is of crucial
+to possess a portable pathname syntax independent of the underlying OS.
+This is what PARSE-UNIX-NAMESTRING provides, and why we use it in ASDF.
+
+When given a PATHNAME object, just return it untouched.
+When given NIL, just return NIL.
+When given a non-null SYMBOL, first downcase its name and treat it as a string.
+When given a STRING, portably decompose it into a pathname as below.
+
+#\\/ separates directory components.
+
+The last #\\/-separated substring is interpreted as follows:
+1- If TYPE is :DIRECTORY or ENSURE-DIRECTORY is true,
+ the string is made the last directory component, and NAME and TYPE are NIL.
+ if the string is empty, it's the empty pathname with all slots NIL.
+2- If TYPE is NIL, the substring is file-namestring, and its NAME and TYPE
+ are separated by SPLIT-NAME-TYPE.
+3- If TYPE is a string, it is the given TYPE, and the whole string is the NAME.
+
+Directory components with an empty name the name . are removed.
+Any directory named .. is read as DOT-DOT,
+which must be one of :BACK or :UP and defaults to :BACK.
+
+HOST, DEVICE and VERSION components are taken from DEFAULTS,
+which itself defaults to *NIL-PATHNAME*, also used if DEFAULTS in NIL.
+No host or device can be specified in the string itself,
+which makes it unsuitable for absolute pathnames outside Unix.
+
+For relative pathnames, these components (and hence the defaults) won't matter
+if you use MERGE-PATHNAMES* but will matter if you use MERGE-PATHNAMES,
+which is an important reason to always use MERGE-PATHNAMES*.
+
+Arbitrary keys are accepted, and the parse result is passed to ENSURE-PATHNAME
+with those keys, removing TYPE DEFAULTS and DOT-DOT.

+optionally doing some transformations and checking specified constraints.
+
+If the argument is NIL, then NIL is returned unless the WANT-PATHNAME constraint is specified.
+
+If the argument is a STRING, it is first converted to a pathname via PARSE-UNIX-NAMESTRING
+reusing the keywords DEFAULTS TYPE DOT-DOT ENSURE-DIRECTORY WANT-RELATIVE;
+then the result is optionally merged into the DEFAULTS if ENSURE-ABSOLUTE is true,
+and the all the checks and transformations are run.
+
+Each non-nil constraint argument can be one of the symbols T, ERROR, CERROR or IGNORE.
+The boolean T is an alias for ERROR.
+ERROR means that an error will be raised if the constraint is not satisfied.
+CERROR means that an continuable error will be raised if the constraint is not satisfied.
+IGNORE means just return NIL instead of the pathname.
+
+The ON-ERROR argument, if not NIL, is a function designator (as per CALL-FUNCTION)
+that will be called with the the following arguments:
+a generic format string for ensure pathname, the pathname,
+the keyword argument corresponding to the failed check or transformation,
+a format string for the reason ENSURE-PATHNAME failed,
+and a list with arguments to that format string.
+If ON-ERROR is NIL, ERROR is used instead, which does the right thing.
+You could also pass (CERROR \"CONTINUE DESPITE FAILED CHECK\").
+
+The transformations and constraint checks are done in this order,
+which is also the order in the lambda-list:
+
+WANT-PATHNAME checks that pathname (after parsing if needed) is not null.
+Otherwise, if the pathname is NIL, ensure-pathname returns NIL.
+WANT-LOGICAL checks that pathname is a LOGICAL-PATHNAME
+WANT-PHYSICAL checks that pathname is not a LOGICAL-PATHNAME
+ENSURE-PHYSICAL ensures that pathname is physical via TRANSLATE-LOGICAL-PATHNAME
+WANT-RELATIVE checks that pathname has a relative directory component
+WANT-ABSOLUTE checks that pathname does have an absolute directory component
+ENSURE-ABSOLUTE merges with the DEFAULTS, then checks again
+that the result absolute is an absolute pathname indeed.
+ENSURE-SUBPATH checks that the pathname is a subpath of the DEFAULTS.
+WANT-FILE checks that pathname has a non-nil FILE component
+WANT-DIRECTORY checks that pathname has nil FILE and TYPE components
+ENSURE-DIRECTORY uses ENSURE-DIRECTORY-PATHNAME to interpret
+any file and type components as being actually a last directory component.
+WANT-NON-WILD checks that pathname is not a wild pathname
+WANT-WILD checks that pathname is a wild pathname
+WILDEN merges the pathname with **/*.*.* if it is not wild
+WANT-EXISTING checks that a file (or directory) exists with that pathname.
+ENSURE-DIRECTORIES-EXIST creates any parent directory with ENSURE-DIRECTORIES-EXIST.
+TRUENAME replaces the pathname by its truename, or errors if not possible.
+RESOLVE-SYMLINKS replaces the pathname by a variant with symlinks resolved by RESOLVE-SYMLINKS.

-;;;; run-shell-command
-;;;;
-;;;; run-shell-command functions for other lisp implementations will be
-;;;; gratefully accepted, if they do the same thing.
-;;;; If the docstring is ambiguous, send a bug report.
-;;;;
-;;;; WARNING! The function below is mostly dysfunctional.
-;;;; For instance, it will probably run fine on most implementations on Unix,
-;;;; which will hopefully use the shell /bin/sh (which we force in some cases)
-;;;; which is hopefully reasonably compatible with a POSIX *or* Bourne shell.
-;;;; But behavior on Windows may vary wildly between implementations,
-;;;; either relying on your having installed a POSIX sh, or going through
-;;;; the CMD.EXE interpreter, for a totally different meaning, depending on
-;;;; what is easily expressible in said implementation.
-;;;;
-;;;; We probably should move this functionality to its own system and deprecate
-;;;; use of it from the asdf package. However, this would break unspecified
-;;;; existing software, so until a clear alternative exists, we can't deprecate
-;;;; it, and even after it's been deprecated, we will support it for a few
-;;;; years so everyone has time to migrate away from it. -- fare 2009-12-01
-;;;;
-;;;; As a suggested replacement which is portable to all ASDF-supported
-;;;; implementations and operating systems except Genera, I recommend
-;;;; xcvb-driver's xcvb-driver:run-program/ and its derivatives.

Fix ticket:72 : SIGFPE with no exceptions enabled
code/float-trap.lisp::
* In the default case, check FOP to see if it's defined. This means
it's a divide exception.
code/x86-vm.lisp::
* Also check to see if the offending instruction is a DIV or IDIV,
which means we got an integer overflow. Return the appropriate
values in this case.
