From: Perl 5 Porters Date: Fri, 20 Sep 1996 14:08:33 +0000 (+0100) Subject: perl 5.003_06: utils/h2xs.PL X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=b73edd974ff6de4630341da3b93d562a24ff05d7;p=p5sagit%2Fp5-mst-13.2.git perl 5.003_06: utils/h2xs.PL Date: Sat, 21 Sep 1996 16:38:24 -0500 From: Dean Roehrich Subject: h2xs bug fix The h2xs that is in perl5.003_05 has a regexp bug which prevents it from finding #define statements and filling the constant() function. This patch fixes that. The h2xs_test program found this--maybe people who are modifying h2xs should get a copy of the test program. This also adds a -d to enable debugging messages (there's just one for now). I've also placed some of the doc-related things in alphabetical order. h2xs_test can be found in my directory on CPAN. Those of you modifying xsubpp should know there's a test suite for that, too, called XSTEST which can also be found in my directory on CPAN.
