Note that I did not have any problem to compile libcpp/lex.c on
powerpc-apple-darwin8 with
gcc version 4.0.1 (Apple Computer, Inc. build 5370):

...
gcc  -I../../work/libcpp -I. -I../../work/libcpp/../include
-I../../work/libcpp/include -I/sw/include -g -fkeep-inline-functions -W -Wall

-I../../work/libcpp/include -I/sw/include -c -o lex.o -MT lex.o -MMD -MP -MF
