gcc:
* config.gcc (hppa*-*-hpux11*, ia64*-*-hpux*): Remove
commented-out logic to use DCE threads (if present), add
support for POSIX threads.
* config/ia64/hpux.h: Define CPP_SPEC to set appropriate
#defines for -pthread. Add -lpthread to LIB_SPEC when
-pthread. In both cases take -mt as a synonym for -pthread
for acc compatibility.
Define GTHREAD_USE_WEAK to 0.
* config/pa/pa-hpux11.h: Likewise for CPP_SPEC and LIB_SPEC.
Remove old logic for DCE threads from LIB_SPEC.
* config/pa/pa64-hpux.h: Define GTHREAD_USE_WEAK to 0.
libstdc++-v3:
* config/os/hpux/os_defines.h: Unconditionally define
_GLIBCXX_GTHREAD_USE_WEAK to 0.
