Include gerror.h before it is used for some g_thread_* functions.

2000-09-01  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* glib.h: Include gerror.h before it is used for some g_thread_*
	functions.

	* gthread.c, gthreadpool.c, glib.h: Enable error reporting for
	thread creation, namly for g_thread_create, g_thread_pool_new,
	g_thread_pool_push and g_thread_pool_set_max_threads.

	* tests/thread-test.c, tests/threadpool-test.c: Adapted
	accordingly.

	* gthread-posix.c (g_thread_create_posix_impl): Use GError to
	report errors.

glib.h
