For quite some time now, I've been tweaking my local copy of gnulib in order
to compile octave with MSVC. I put the current diff I have (not against the
very latest source, maybe gnulib from about 1 week ago). It is *not* meant
to be a ready-to-use patch, but more to illustrate the problems I had:
- O_ACCMODE is not defined
- PATH_MAX is not defined (though stdlib.h has an equivalent _MAX_PATH)
- ending a path with double slashes lead to problems (don't remember which
ones, but Windows didn't like it)
- MSVC does not support dynamic C array: array size must be a constant,
not a variable
- ssize_t does not exist
- rename m4 test produced filesystem corruption that lead to full recheck on
the next reboot; I had to disable the test completely

I hope this will be useful.
