The problem stays (I am now on a second machine, but same system Debian

After stripping off the compiler options, the command line is

x86_64-w64-mingw32-gcc-win32 -DHAVE_CONFIG_H -I. -I..
-I/home/tim/src/wget2/x86_64-w64-mingw32/include -no-integrated-cpp
-DNDEBUG -fno-PIC -MT fatal-signal.lo -MD -MP -MF .deps/fatal-
signal.Tpo -c fatal-signal.c  -DDLL_EXPORT -DPIC -o .libs/fatal-

In the -E output there is
# 593 "./signal.h" 3
extern int 0

Line #593-594 in signal.h is:
_GL_FUNCDECL_SYS (pthread_sigmask, int,
                  (int how, const sigset_t *new_mask, sigset_t

I am using glthreads.
Maybe that has to do with the configure flag --disable-threads !?
The glthread functions are defined a 0 in this case.

The surrounding code in signal.h looks like
#if 1
# if 0
#  if !(defined __cplusplus && defined GNULIB_NAMESPACE)
#   undef pthread_sigmask
#   define pthread_sigmask rpl_pthread_sigmask
#  endif
_GL_FUNCDECL_RPL (pthread_sigmask, int,
                  (int how, const sigset_t *new_mask, sigset_t
_GL_CXXALIAS_RPL (pthread_sigmask, int,
                  (int how, const sigset_t *new_mask, sigset_t
# else
#  if !0
_GL_FUNCDECL_SYS (pthread_sigmask, int,
                  (int how, const sigset_t *new_mask, sigset_t
#  endif

Any more ideas / hints ?
