That's odd. Could you show me the output of the following? I suspect
that your GCC might not like the combination of -E with some other
compiler flags. Otherwise I don't see why it does not detect GCC 4.x.
cat >try.c <<EOF && gcc -E try.c | grep '^gcc_'
int main(void) {
#ifdef __GNUC__
gcc_version_major __GNUC__
#ifdef __GNUC_MINOR__
gcc_version_minor __GNUC__
#endif
#ifdef __GNUC_PATCHLEVEL__
gcc_version_patchlevel __GNUC_PATCHLEVEL__
#endif
#endif
}

Do you really have to pass --make=/usr/bin/make?
