Yes, it could be harmful: many programs originally developed on Unix
look at the macros defined by the ifdef-ed-out part of ioctl.h and
assume that the related functionality in the library exists.  But
DJGPP doesn't yet support the Unix ioctl commands, so you will have
programs that compile and maybe even link, but either crash or do
other wrong things at run time.

So don't do that.

If you have specific problems with the ioctl.h macros, please explain
each one of them separately, and someone might suggest a work-around
for you.
