* Makefile.in (GNULIB_TOOL_FLAGS): Do not avoid sigprocmask. * configure.in (AC_TYPE_UID_T): New dummy macro. Configure gnulib after adjusting LIBS, so that gnulib can assume the libraries in LIBS. * lib/pthread_sigmask.c, lib/sigprocmask.c, m4/signalblocking.m4: New files, automatically imported from gnulib. * lib/gnulib.mk, m4/gl-comp.m4: Regenerate. * src/Makefile.in (LIB_PTHREAD_SIGMASK): New macro. (LIBES): Use it.

# Determine available signal blocking primitives. Three different APIs exist:
|
|
# 1) POSIX: sigemptyset, sigaddset, sigprocmask
|
|
# 2) SYSV: sighold, sigrelse
|
|
# 3) BSD: sigblock, sigsetmask
|
|
# For simplicity, here we check only for the POSIX signal blocking.
