Yes, it's seldom that one needs all of it.

Currently, I'm using these modules for w32 compat:

canonicalize
errno
execute
fsync
getdelim
gethostname
getline
mkdir
netdb
progname
readlink
regex
scandir
sigaction
signal-h
strcasestr
strsep
sys_wait
time_r
timegm 
waitpid
xvasprintf

(some of which you already have implemented)

but those modules in turn depend on other gnulib modules, so you'd end
up with:

Of course, you'd also need the configure checks to enable/disable
compiling those modules. Doing this without gnulib-tool / autotools
seems to be a lot of (gratuitous) work.

I don't think that I'll have to time to do this, so I'll just keep my
patches in a private branch then, which saves me the effort of
polishing the patches.

Thanks for your attention.
