Literally, you're trying to feed 'C' to the assembler.

At first I figured that the weak_alias() macro should not be
allowed in .S files.  However, I see for mips only, fork.S does
this.  Probably it is a slip up.  If you look in v860/ & sh/
Makefile's they have:

    sh/Makefile:SFLAGS= $(CFLAGS) -D__ASSEMBLER__ ...

I suspect mips/Makefile should have this.

If the weak_alias(clone) is actually needed, by inspecting other
arches .S files you can see the assembly syntax is:

v850/longjmp.S:
    .weak C_SYMBOL_NAME(longjmp)
    C_SYMBOL_NAME(longjmp) = C_SYMBOL_NAME(__longjmp)

You've included CVS files in your diff.  :-/
Use '| filterdiff -x "*CVS*"' before posting.
