It's not clear to me why the compiler should be involved in providing this
functionality.  Can the assembler simply support '-mcode16gcc' command-line
flag, which would have the effect of enabling .code16gcc for the whole
translation unit?  That way, you could simply add -Wa,-mcode16gcc to the GCC
command line and avoid the need to patch the compiler.  Am I missing
something?

Thanks.
