Is this "us" or "them"?

[Phil Edwards]

I'm working on one of my pet peeves[*], trying to make our configure script
smaller and faster.  With current CVS of everything, I'm getting this at
the end of the run, when building gen-num-limits:

   /stuff/pme/3test/gcc/include/limits.h:133: warning: badly nested C headers from preprocessor
   /usr/include/float.h:100: warning: badly nested C headers from preprocessor
   /usr/include/stdio.h:401: warning: badly nested C headers from preprocessor
   /usr/include/signal.h:245: warning: badly nested C headers from preprocessor
   /usr/include/setjmp.h:69: warning: badly nested C headers from preprocessor
   /stuff/pme/3test/gcc/include/math.h:10: warning: badly nested C headers from preprocessor
   /usr/include/wchar.h:143: warning: badly nested C headers from preprocessor

Is this A) something we've been doing all along that is just now exposed,
or B) a bug in the current cpp, or C) platform-specific Solaris stupidity
just now exposed?
