Hello,

I'm sorry that I reply to my own mail, but I think I have invented a
very simple solution:

AC_LANG_COMPILER(XYZ) would be m4_defined and
AC_LANG_COMPILER_REQUIRE would always call it.
It would be obligatory that AC_LANG_COMPILER(XYZ) can contain
AC_REQUIRE calls only.

I'll investigate this and hopefully come back with a patch soon.
