1: /-- This set of tests is not Perl-compatible. It checks on special features
2: of PCRE's API, error diagnostics, and the compiled code of some patterns.
3: It also checks the non-Perl syntax the PCRE supports (Python, .NET,
4: Oniguruma). Finally, there are some tests where PCRE and Perl differ,
5: either because PCRE can't be compatible, or there is a possible Perl
6: bug.
