Hmm, not sure what you mean by this.  I can't find this
macro definition in autoconf 2.13 or CVS.  

Basically, all I need is a portable way (autoconf 2.13 and
autoconf >= 2.5) to determine what the current language is.
In 2.13, AC_LANG is set to "C" or "CXX".  But this variable
is no longer set in 2.5 and greater.  Instead, the macro
_AC_LANG_ABBREV is set.  What I need is a way to determine
the current language in both versions. I'd prefer not to
have to add AC_REQUIRE([2.52]) to my custom m4 macros.
