peti_pedantic_gcc

For development purposes, it is desirable to have autoconf automatically enable warnings when compiling C or C++ sources. In case the underlying compiler is a gcc, the appropriate flags are "-Wall -pedantic". This macro will add them to $CFLAGS and $CXXFLAGS if $CC is found to be a gcc.
