Log message:
        Set AC_LANG_PREPROC_REQUIRE which replaces AC_REQUIRE_CPP.
        The main difference is that the former requires AC_LANG_COMPILER.
        * aclang (AC_LANG_PREPROC, AC_LANG_PREPROC(C), AC_LANG_PREPROC(C++))
        (AC_LANG_PREPROC(Fortran 77), AC_LANG_PREPROC_REQUIRE): New
        macros.  Issue a warning when looking for the Fortran 77
        preprocessor instead of an error.
        (AC_LANG_COMPILER): Check that it is run before the corresponding
        AC_LANG_PREPROC.
        (AC_PROG_C
        (AC_LANG_COMPILER_REQUIRE): Don't call directly
        AC_LANG_COMPILER(_AC_LANG), rather invoke AC_LANG_COMPILER so that
        the generic code in AC_LANG_COMPILER is run.
        (AC_REQUIRE_CPP): Use AC_LANG_PREPROC_REQUIRE.
        (AC_PROG_CC, AC_PROG_CXX): Don't require being run before the
        corresponding AC_LANG_PREPROC: AC_LANG_COMPILER does it.
        Propagate AC_LANG_PREPROC_REQUIRE.
        * acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP): Use it instead of
        AC_REQUIRE_CPP.
        * acspecific.m4 (_AC_DECL_YYTEXT, AC_PATH_X): Don't
        AC_REQUIRE_CPP, inner macro will do it.
        * aclang.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_STRINGIZE)
        (AC_C_PROTOTYPES): Likewise.
        (AC_C_STRINGIZE): Yeeks!  The body of AC_CACHE_CHECK was not
        quoted.  Use @%:@ do assist Emacs.
        For some reason (don't ask), this revamping revealed that
        AC_PROG_CC_STDC, because of the `break', does not clean its tmp
        files.
        * aclang.m4 (AC_PROG_CC_STDC): Extract the creation of conftest.c
        out of AC_COMPILE_IFELSE.
        Be sure to clean the tmp files.
