Well, I used gcc 1.36 on perl and it worked just fine.  There were a
couple gotchas, though.  eval.c and toke.c both had to be compiled with
the standard cc; this is easy enough.  (Modify the makefile and add
these lines:

eval.o: eval.c
	cc -c -O $(LARGE) eval.c

toke.o: toke.c
	cc -c -O $(LARGE) toke.c

right before the perl.man lines.)  The other gotcha is reflected in the
makefile already:  you need to use -fpcc-struct-return so that the gcc
binaries will be able to pass structs to code compiled with the standard
compiler.  With these modifications, plus corrections to fix the pw_
stuff, perl passed all but one test, op.mkdir #3.  If you want the exact
mods to fix the pw_ stuff, let me know.
