  Wise.  I tried to bully my way through it and got sock of it though.

  In addition to Ben Collins's gcc-glibc-2.2-compat.diff patch, I had to
add this one (attached) to a stock gcc-2.95.2 to get it to compile.
With it, I'm able to compile glibc (-2.1.94) with gcc-2.95.2 (patched)
and then turn around and recompile gcc under glibc (which I couldn't do
before, with the errors you yourself have seen).

  I finally had to dump egcs-20000828 because it was going to cause me to
have to patch too many programs.  99% of the problems were bad porting
(primarily bad prototypes), but they also did some things like drop
-traditional.  That is when I dropped the snapshot.  ):
