GCC doesn't process assembler files; it just passes them to the
assembler, which is part of binutils. However, it may be that GCC puts
the preprocessor into a special mode when preprocessing a .s file.
Please investigate and report back!

In any case, TCC does not need, and should not have, a
"-fno-hex-floats option" option.
