threads on the HPUX.

threads on the HPUX.

[Arvind Sankar]

The latest 2-3 snapshots(including 19980418) have some exception
handling routines which require pthread_* functions. On my HPUX system,
lots of g++ tests fail because about 4-5 of these functions are not
linked in. I can't figure out why: I looked in the specs file, and
libcma.a (from the DCE threads package) is supposed to be linked in with
-threads, but the tests don't specify it. Why do the eh routines require
thread functions even without -threads?

To get the tests working, I tried adding libcma.a to libgcc.a, but this
results in _all_ executables getting the full cma library, which bloats
the executable unacceptably.

I configured egcs with
/test1/arvind/egcs-19980418/configure --host=hppa1.1-hp-hpux10.20
	--prefix=/pkgs/egcs --with-gnu-as --verbose
