I agree that non-Posix functions should not be used.

This is nice, but not necessary: most of the programs used in the
DJGPP development don't bother to do that (it's not needed on Unix,
usually).

That would be incompatible with the original version: it returned
non-zero exit status when, for example, one of the files didn't exist
or couldn't be open/read.
