GCC 4.4 at least for mips has no -Wsuggest-attribute=pure

[Vladimir 'φ-coder/phcoder' Serbinenko]

Which makes compilation fail in regex.c on
 # if (__GNUC__ == 4 && 3 <= __GNUC_MINOR__) || 4 < __GNUC__
 #  pragma GCC diagnostic ignored "-Wsuggest-attribute=pure"
 #  pragma GCC diagnostic ignored "-Wtype-limits"
 # endif
