As the documentation clearly states, AC_REQUIRE expects a macro NAME;
that macro will then be called _without arguments_ if it has not already
been called.
So you want 'AC_REQUIRE([AC_PROG_CXX])'; in order to look only for
certain compilers, simply place the 'AC_PROG_CXX(CC g++ gcc)' call
before the AC_REQUIRE'ing macro in configure.ac.
