Description Charlie & 2002-08-02 01:10:01 UTC 
Problem with libc_r.
Compiling using gcc with the -pthread switch yields the following error:

wade@archeron-~:gcc -pthread test.c 
/usr/lib/libc_r.so: undefined reference to `__sys_close'
wade@archeron-~:
	

I have not been able to repeat this problem on my next-newest build:
	FreeBSD ylw.noc.dbitech.bc.ca 4.6-STABLE FreeBSD 4.6-STABLE #0: Mon Jul 15 08:08:23 PDT 2002     root@ylw.noc.dbitech.bc.ca:/usr/src/sys/compile/WORKSTATION  i386

Fix: 

I have verified this on 3 boxen all cvsup'd today.
Compile the following program with the -pthread switch:

  test.c
----------

main(){}

	

Do not compile re-entrant programs.

Over to committer that touched uthread_dup2.c last.  I believe the problem 
can be resolved by changing line 74 of uthread_dup2.c to read: 

_thread_sys_close(ret);

I'm in the middle of this code right now; I'll fix this.
