That was a good suggestion, but I'm afraid the answer is "no." No handling of cygwin in trivial-features.

Unfortunately, there's also no :CYGWIN feature in *FEATURES*, at least not in the February release I just installed on my VM.

Best, r

Is there some way that a CL implementation can know whether it is running under a Unix-alike like Cygwin or MinGW?

If we use RUN-PROGRAM to interrogate the environment, we do so using CMD.exe, so I'm not sure how CMD.EXE would know if it was being run as the grandchild of a bash process.

AFAICT Cygwin (and I don't know about MinGW) don't put anything into their environments that I can obviously see. E.g., if I start a lisp inside cygwin and do (GETENV "OS") I just see "Windows_NT".

Thanks, r

Just curious, does anyboy know, how many lispers runs Lisp under Cygwin?

Note that from my POV there are 2 issues here:

1. ASDF should run correctly under cygwin.

2. At the moment, the only way I know of to run the tests on Windows is through Cygwin, since they are based on make and a shell script.

It is possible that at least #2 could be eased by running under MinGW, but I have never used MinGW. It sounds like it might not have as many pathname incompatibilities as Cygwin.

I don't know if I can install MinGW without breaking my Cygwin install. I'd hate to mess up my (extremely brittle and rickety Windows VM). Any advice (probably off-list would be best) would be much appreciated.

thanks, r
