RE: [PATCH v3 10/13] don't check for unistd.h

["Pierre Muller" <pierre dot muller at ics-cnrs dot unistra dot fr>]

  Hi,

  I am not totally sure this is related,
but I got a new error when trying to cross compile
for i686-w64-mingw32 using cygwin.
m32r-rom.o: dans la fonction « m32r_upload_command »:
/home/Pierre/git/build/binu-gdb-mingw32/gdb/../../../binutils-gdb/gdb/m32r-r
om.c:472: référence indéfinie vers «
_imp__gethostname_used_without_requesting_gnulib_module_gethostname@8 »
collect2: erreur: ld a retourné 1 code d'état d'exécution

I tried to run ./config.status --recheck; make
but that did not solve the problem...

To double check, I completely erased the build directory
and reran the "../build/XXX/configure" with required options
and  "make all-gdb": Same error...

Could someone double-check if this is a general problem
with mingw target?

How could this problem be solved?

Pierre Muller
