Regex: Add PCRE 8.32 in tools directory.
2014-07-04 22:28:24 +00:00
/-- This set of tests is for features that are compatible with all versions of
Regex: Update PCRE to v8.35. I was über lazy at first, so took libs from SM. But actually it's quite easy to compile, so let's update to latest version \o/.
2014-07-05 11:53:30 +00:00
Perl >= 5.10, in non-UTF-8 mode. It should run clean for the 8-bit, 16-bit,
and 32-bit PCRE libraries. --/
