Possibly, there are several correct answers.

On one hand, I may have been wrong to have used a private(?) -
underscored - interface. I am not an autoconf expert, so I did
what worked for me on several systems I used. If there is a clean
way to rewrite that routine - suggestions are most welcome.
The piece of code in question (used to override header #ifdefs):

m4_define([__AC_UNDEFINE],[_AC_DEFINE_UNQUOTED([#ifdef $1
  #undef $1
#endif])])

On another hand, this routine is part of autoconf and should be
visible to parsed applications. Possibly then, your autoconf is
too old. Is it possible to update it on your system or use some
privately updated build? I guess for your OS it is a replacable
third-party application with few if any OS dependencies.
