I applied some changes to grovel.lisp that seem to fix the problem with the groveler. The problem was that (directory-namestring ...) doesn't include the device name that is used for the drive letter (this is at least true for ccl and ecl on windows 7 64bit). That is the drive letter is missing in the namestring and neither the cffi install directory nor the lib is found by the compiler and so on. This patch may be a little improvisational but thats due to the little time i spend with lisp programming yet. I send the path as attachment.

There is still a problem with osicat after applying the patch but this seems osicat related:

I hope this may help,

When I tried to load the osicat library via quicklisp yesterday i got an
error because the cffi-groveler couldn't find the c compiler and because the
path in the include parameter was ill formed (the drive letter was missing).

Regarding the first issue, unless Windows has some new concept of a
default system compiler, I guess all we can do is look for more likely
places. Right now, it's looking at "c:/msys/1.0/bin/gcc.exe". Perhaps
it could do better than that.

It is fine to use the CC environment variable, but it would be nice if there was any note in the manual that the variable is important.

What include parameter are you referring to? Do you have a patch?

Osicat is probably the best test-case for cffi-grovel on Windows.
There's also a port of iolib to Windows:
