Possiblility 1. Fixincludes/fixproto is simply running on the wrong set of
headers (this can be checked by looking at the value of SYSTEM_HEADER_DIR in the gcc
Makefile, which should refer to the correct header directory).
Possibility 2. A fixincludes hack is demolishing stdlib.h.  (Run fixincludes
by typing 'make stmp-fixinc' in the gcc/ directory, and see if there are lines
saying 'Fixed: stdlib.h'.  Those hacks will be the possible culprits.)
Possibility 3. It's being trampled post-fixincludes, by fix-header.c/fixproto.
(this seems unlikely, but is possible).

The solutions are quite different in the three cases, so if it could be determined for sure which one was going wrong, it would help a lot in 
tracking this down.
