[PATCH] Correct docs on obsolete constructs

[Eric Blake]

This threw me in the manual, section 15.4.  When I followed it literally to 
get rid of the -Wall warning in my configure.ac, the method body was being 
silently discarded because the docs pointed me to the wrong replacement 
macro.  For that matter, is it worth trying to make AC_LANG_SOURCE warn if 
it receives a non-empty second argument, since it will discard it?

Someday, I might put a cute statement here.
