Here's a patch that I plan to install to simplify Emacs based
on assuming that the underyling system supports POSIX 1003.1-1988
or later with respect to unistd.h. This is universal these days
on GNUish hosts, and I don't forsee any problems with Microsoft
hosts. I'm CC:ing this to Eli, though, to give him a heads-up
just in case.
It may help in a later patch to simplify the Microsoft side by
removing getwd and standardizing on getcwd, since that's what
POSIX did back in 1988, but that's an issue that's independent
of this patch.

It's not independent. The getwd in w32.c must be modified to be
getcwd instead.
Otherwise, I see no problems with this, as far as the MS-Windows build
is concerned.

the following. I'm attaching a combined patch, relative to trunk bzr
110966. Also, how is this related to the "#define getcwd _getcwd" in

This should be removed entirely, since there are no HAVE_GETCWD tests
