Re: _AC_PROG_CXX_EXIT_DECLARATION problem

I've narrowed this down further. It appears to be a problem with 
autoconf.m4f. If I move autoconf.m4f to autoconf-hold.m4f, regenerate 
my configure, configure works right. I'm not into internals of 
autom4te stuff--so is there something I should check? Why would this 
make a difference? I looked in the autoconf.m4f file and it appears 
to be the same code that is in c.m4 for the function.

Any pointers?
