Appears to be invalid code produced when -mthumb selected.
Happens with gcc 4.1.1 and 4.2.2 when compiling with:
arm-rtems4.9-gcc -mcpu=arm7tdmi -mthumb -O2 -c /tmp/test1.c
/tmp/cccISkv7.s: Assembler messages:

Assembler was invoked as
/opt/rtems-4.9/lib/gcc/arm-rtems4.9/4.2.2/../../../../arm-rtems4.9/bin/as -mcpu
=arm7tdmi -mfpu=softfpa -o test1.o /tmp/cc7F7jPZ.s
When I compile test2.c, it gives errors about duplicate type definitions. That
is the same file with cpp comments removed. Strange.
