That's exactly what gnulib is - a library of source code workarounds for
broken platform functions.  Are you interested in porting your
libsuacomp fixes into gnulib, so that more GNU programs can support
Interix out of the box?

Agreed - that is the approach that most GNU projects take - isolate the
platform bugs into wrapper function fixes, so that the rest of the
project can assume sane POSIX semantics.
