Avoid triggering "gcc internal compiler error"

The Devel-NYTProf-4.09 (and later) fails to build on Fedora Core 4 with
perl-5.16. Both perl-5.14 and perl-5.18 avoids triggering this bug.

We are building ActivePerl on fairly old Linux boxes which we don't really want to upgrade.
It's probably the case that newer versions of gcc has fixed this problem.
