------- Comment #2 from steven at gcc dot gnu dot org 2006-07-24 05:46 -------
gcc -v shows that only the last -fno-builtin-* is passed to cc1:
$ /xgcc -B. -fno-builtin-iswalpha -fno-builtin-iswalnum -c b.c -v
Reading specs from ./specs
Target: x86_64-unknown-linux-gnu
Configured with: ../trunk/configure --enable-languages=c,c++,objc,fortran
Thread model: posix
gcc version 4.2.0 20060723 (experimental)
./cc1 -quiet -v -iprefix
/home/steven/devel/build-trunk-test/gcc/../lib/gcc/x86_64-unknown-linux-gnu/4.2.0/
-isystem ./include t.c -quiet -dumpbase t.c -mtune=generic -auxbase t -version
-fno-builtin-iswalnum -o /tmp/cc6JyivL.s
(etc.)
Likewise for cc1plus.
