The only problem which gethostname module fixes is:
On mingw, this function has a prototype that differs from that
specified by POSIX, and it is defined only in the ws2_32 library.
why does it have such extensive dependencies? (sockets! errno!)
I have to reiterate my complaint that the gnulib dependencies mean that one has
to include (almost) the whole of gnulib if one includes (almost) any part thereof.
the case in question is that I am now getting
undefined reference to
`_gethostname_used_without_requesting_gnulib_module_gethostname'
gcc errors on mingw and I have to figure out which gnulib module did this to me.
