This patch to Makefile makes git build for me on Tru64/OSF1 V5.1 with
the native compiler.

I wonder if the native compiler will be the most common compiler
used on this platform?  I tend to lean towards configuring the
Makefile for gcc, unless gcc is not available for a platform. The
user can set CC and CFLAGS in config.mak and on the make command
line if they desire something different.

This isn't an objection by me, I'm just mentioning it to bring
attention to the issue in case others think it is worthy for
git to have a stated policy one way or the other.

I'm not certain. I do in fact have gcc (3.3) installed on this Tru64
box, but it doesn't seem to be part of the original 'freeware' CD that
used to come with Tru64. Besides, the freeware CD was first removed as
physical CD, and later (two or three years ago, apparently) pulled by
HP from the online download which was used by their 'tachometer'
('apt-get'-like) freeware tool. Tru64 V51B (which seems to be the
latest, there's no 5.2 as I originally thought) is still available for
download, and so is the native compiler. As far as I can tell it's
incredibly difficult to find precompiled freeware/oss packages for
Tru64 anymore.

Can you run the test suite with this ksh?  If it suffers from
the same exit status behavior of ksh on IRIX and SunOS, then
I have a patch which allows the test suite to run.

Good idea. I'll do that, and maybe that would indicate if there are
issues with using the native compiler as well.

Also, I wonder if it suffers from the same trap handling that
ksh has on SunOS.

I tested that snippet you provided, and it exits with 0 on Tru64 (I
also verified that indeed it doesn't on Solaris 10).

There is a PTHREAD_LIBS variable and it seems there is precedent
for setting it to -pthread in the FreeBSD section.

Right, I can do it similarly in my next version of the patch. Thanks
for your comments!
