OK, piling hack upon hack to get things to work, I've got 4 tests that
don't pass:
	-rwxr-xr-x 1 aidan group  5733 Jan 23 20:57 t/t5302-pack-index.sh
	-rwxr-xr-x 1 aidan group  4204 Dec  4 15:21 t/t5400-send-pack.sh
	-rwxr-xr-x 1 aidan group  4321 Dec  4 15:21 t/t7003-filter-branch.sh
	-rwxr-xr-x 1 aidan group 16846 Jan 23 20:57 t/t9500-gitweb-standalone-no-errors.sh

git-pack-objects is segfaulting:
	~/software/git.git/t/trash$ git-pack-objects test < obj-list
	Counting objects: 102, done.
	Compressing objects: 100% (101/101), done.
	Segmentation Fault

Stack trace:
	SIGNALED 11 (segv code[SEGV_MAPERR] address[0xbff68008]) in p1
	184:    <no source text available>
	debug> stack

	 [3] cmd_pack_objects() [�\@builtin-pack-objects.c@2245]

Before I dig too deeply, does that look familiar to anyone?

Just FYI, my current stack of hacks is:
	HACK: BROKEN_FOPEN
	HACK: BROKEN_VSNPRINTF
	HACK: strtoul
	NO_RSYNC to avoid mkdtemp

An interesting one is the strtoul HACK:
	diff --git a/builtin-unpack-objects.c b/builtin-unpack-objects.c
	index 1e51865..2c2e187 100644
	--- a/builtin-unpack-objects.c
	+++ b/builtin-unpack-objects.c
	@@ -368,7 +368,11 @@ int cmd_unpack_objects(int argc, const char **argv, const char *prefix)
					hdr->hdr_version = htonl(strtoul(arg + 14, &c, 10));
					if (*c != ',')
						die("bad %s", arg);
	-                               hdr->hdr_entries = htonl(strtoul(c + 1, &c, 10));
	+{      /* Another ugly SCO hack */
	+char*d;
	+                               hdr->hdr_entries = htonl(strtoul(c + 1, &d, 10));
	+c = d;
	+}
					if (*c)
						die("bad %s", arg);
					len = sizeof(*hdr);

Is this just a *completely* broken compiler?  With out this hack,
"c" is set to something farther ahead then the null at the end of the
"--pack-objects=2,10", and the if (*c) test obviously fails (and the
value read by the strtoul isn't correct either).

I've verified that the c *is* ",10" before entering that line... and I
can't see any reason why that wouldn't "just work", but hey, this is
SCO.
