DJGPP defines __GO32__, that's why the above gets excluded.

If the DJGPP version calls _dos_creat to create a label, it looks like
a small wonder that it fails when there's already a label on the disk,
right?

You could try rewriting the code which uses intdosx like I suggested
in my previous message; perhaps calling function 17h is the solution,
and whoever used _dos_creat simply didn't know how to call such
functions from a DJGPP program?

It probably got left over from early DJGPP versions.  The symbol
__DJGPP__ was only added in DJGPP v2.0.
