[PATCH] Unresolved symbol in ext/re/re.xs

If the re module is used in some module test then it might fail with:

   Can't load '../../lib/auto/re/re.so' for module re: ../../lib/auto/re/re.so: undefined symbol: Perl_deb at ../../lib/XSLoader.pm line 75.

The reason is that MakeMaker runs the test with PERL_DL_NONLAZY.  The
quick way to provoke this failure is simply by running:

   PERL_DL_NONLAZY=1 perl -Mre=debug -e1

The patch below fixes the problem.  It is relative to perl-5.6.1.

Regards,
Gisle
