The old Solaris threads facility was needed for portability to the
ancient Solaris 2.4. Solaris >= 2.5.1 has POSIX threads.
Even though Solaris nowadays probably still supports this API, you can
bet that 100% of all applications use the POSIX threads API. There is
no point in --enable-threads=solaris any more.
Since this code is in the way of unifying the thread, lock, cond, tls
modules with the 'pthread' module, I'm removing it.
2019-07-05 Bruno Haible <address@hidden>
thread, lock, cond, tls: Remove support for old Solaris threads.
Solaris >= 2.5.1 has POSIX threads.
* m4/threadlib.m4 (gl_THREADLIB_EARLY_BODY): Don't document
--enable-threads=solaris any more.
(gl_THREADLIB_BODY): Don't set USE_SOLARIS_THREADS any more.
* lib/glthread/thread.c: Update comment.
* lib/glthread/thread.h: Remove code for USE_SOLARIS_THREADS.
* lib/glthread/lock.h: Likewise.
* lib/glthread/lock.c: Likewise.
* lib/glthread/cond.h: Likewise.
* lib/glthread/cond.c: Likewise.
* lib/glthread/tls.h: Likewise.
* lib/glthread/tls.c: Likewise.
* lib/glthread/yield.h: Likewise.
* lib/regex_internal.h: Likewise.
* tests/test-thread_create.c: Likewise.
* tests/test-lock.c: Likewise.
* tests/test-cond.c: Likewise.
* tests/test-tls.c: Likewise.
