RE: POSIX compliance: pthread_mutex_destroy()

The attached patch to the pristine ngpt-2.2.0 fixes this. Apply it to
the 
clean ngpt-2.2.0 tarball, rerun ./configure, and rebuild to resolve it.

Subject: [pthreads-users] POSIX compliance: pthread_mutex_destroy()

hello,

I am working on the Open POSIX Test Suite project at
http://posixtest.sourceforge.net
I ran the POSIX compliance tests upon 

ngpt-2.2.0
kernel-2.4.18
glibc-2.2.93-5

There seemed to be an error in the function pthread_mutex_destroy(),
where
the test failed because pthread_mutex_destroy() did not successfully
destroy
a mutex initialized using PTHREAD_MUTEX_INITIALIZER, it instead returned
EINVAL (22).

The test that I am using to reproduce this issue is part of the POSIX
Test
Suite project http://posixtest.sourceforge.net under
posixtestsuite/conformance/interfaces/pthread_mutex_destroy/1-1.c
(pasted
the code below)

Error message received was: "Fail to destroy mutex3, rc=22"

thanks,

Rolla Selbak
