Even so, all GCC-compiled C code internally assumes DS=ES, all the
time.  If you don't want that, you can't use DJGPP for your
application.

No, it's an inlined C function, consisting of a single inline assembly
block.  That's a different thing from a simple asm macro. In
particular, this construct allows for these to be used from optimized
C code.

I know you want that. But as I already said: you can't have it.
