Subject: Not OK: perl 5.00555 on i386-svr4 [actually Unixware 2.1] (UNINSTALLED)

AIX syscalls.exp scan: the syscall might be marked 32, 3264, or 64

From: Joe Buehler <jhpb@hekimian.com>
To: perl5-porters@perl.org
Subject: setsid not detected by perl 5.005_02 configure under AIX 4.3
Date: 12 Feb 1999 11:25:21 -0500
Message-ID: <yd3lni3613i.fsf@ganymede.hekimian.com>

Make the pthreads joinable constant scan to output to fd 4, not 2.

 Perl can be built to take advantage of threads, on some systems.
 To do so, Configure must be run with -Dusethreads.

-Note that threading is a highly experimental feature, and
-some known race conditions still remain.  If you choose to try
-it, be very sure to not actually deploy it for production
-purposes.  README.threads has more details, and is required
-reading if you enable threads.
