Compiling PCRE 8.35 with C++ (gcc 4.8.3 20140227 (prerelease)) produces
following compiler warning:
CXX libpcrecpp_la-pcrecpp.lo
pcrecpp.cc: In member function ‘int pcrecpp::RE::TryMatch(const
pcrecpp::StringPiece&, int, pcrecpp::RE::Anchor, bool, int*, int) const’:
pcrecpp.cc:514:41: warning: missing initializer for member

pcre_extra extra = { 0, 0, 0, 0, 0, 0 };

pcre_stringpiece_unittest.cc:144:5: warning: unused parameter ‘argv’
[-Wunused-parameter]
To avoid the unused parameter warnings, you can write within the funcktion
(void)argc; (void)argv;
and likewise, for the other places
