Thankfully, I haven't had to deal with that OS in quite some

No. But it is annoying to be forced to upgrade every second package. If 
there'd be some real benefit, then okay, I'd do it. But there is really no 
point in not supporting the old version.

Besides, in some environments you are just not allowed to go wild 
installing programs. And in some environments, you just don't have the 
quota.

Hth,

I am not opposed to avoiding $(call), but subst everywhere look
ugly ;-).

You inherited this problem, but these two symbols in different
Makefiles with the same name mean two completely different
things, which confused me quite badly.

So if we were to do this portability fix, how about consistently
defining it without surrounding sq pair?  Most of the places in
the main Makefile you use the symbol with other string, with the
whole thing quoted inside a sq pair, so that would make things
easier to read.

Then the one that uses it in the t/Makefile in 5/5 becomes:

        $(T):
                @echo "*** $@ ***"; '$(SHELL_PATH_QUOTED)' $@ $(GIT_TEST_OPTS)

	Agreed. But I think it is a minor hassle for few, and an 
	improvement for	more.

	Fixed. Tested. Works.
