Just in case I was not clear the first time.
I don't need 16-bit relocation in COFF, but I do need .code16

Just replace assert() with an error message.
It maybe either
"16-bit relocation is not yet supported for COFF targets"
or
"16-bit relocation is impossible in COFF object files"
dependent on what is true :-)

But please don't disable ".code16" for COFF !!!
