That would make sense. `perl` in t9700-perl-git.sh (and all of our
scripts) is actually a shell function:
perl () {
command "$PERL_PATH" "$@"
}
to make sure we respect PERL_PATH everywhere. And that defaults in the
Makefile to /usr/bin/perl. Christian presumably has 5.14 in his $PATH,
but /usr/bin/perl is the system 5.10.
One workaround would therefore be for him to tweak PERL_PATH, but
obviously that does not help anyone else. I think we should do this:

Subject: t9700: fix test for perl older than 5.14
Commit d53c2c6 (mingw: fix t9700's assumption about
directory separators, 2016-01-27) uses perl's "/r" regex
modifier to do a non-destructive replacement on a string,
leaving the original unmodified and returning the result.
This feature was introduced in perl 5.14, but systems with
older perl are still common (e.g., CentOS 6.5 still has perl
5.10). Let's work around it by providing a helper function
that does the same thing using older syntax.
While we're at it, let's switch to using an alternate regex
separator, which is slightly more readable.

And yes, before anyone checks, the alternate separators are available
even in ancient versions of perl. :)
