Well... We could do a preprocessor-based test in configure. Something like:
--- cut ---
if test $gl_cv_func_pthread_sigmask_in_LIBMULTITHREAD = yes; then
dnl pthread_sigmask is available with -pthread or -lpthread.
AC_PREPROC_IFELSE([AC_LANG_SOURCE([[
#include <signal.h>
#ifdef pthread_sigmask
#error is a macro
#endif
]])],
[
LIB_PTHREAD_SIGMASK="$LIBMULTITHREAD"
],
[
HAVE_PTHREAD_SIGMASK=0
REPLACE_PTHREAD_SIGMASK=1
])
--- cut ---
Would that do ?
