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