Re: Patch for C preprocessor supporting __func__ or __FUNCTION__

[Steven G. Johnson]

Note that __func__ is an identifier defined by the C compiler; it is not 
a macro according to the standard, and therefore has nothing to do with 
the C preprocessor.

There is an AC_C_VAR_FUNC in the autoconf macro repository.  I suggest 
that you coordinate with the author of this macro before submitting a patch.

(I'm not sure if anyone has articulated a general policy for 
when/whether macros from the repository are included in autoconf proper. 
 This would be helpful, Akim.)
