Actually it is the *compiler* which has to be able to handle prcompiled
headers. The compiler used by DJGPP is GCC which is developed by the folks
at the FSF <www.gnu.org>. So if GCC supported pre- compiled headers then
DJGPP would also automatically support precompiled headers.

So the issue of adding  precompiled headers to GCC should be in the hands
of the guys at FSF not DJGPP.

It is the responsibility of the compiler to support precompiled headers.

No, since even the addon (RSXNTDJ) is really a extension of DJGPP which
enables the creation of windoze executables.

So as you can see it is the duty of the writers of the compiler (gnu.org)
to add the pre-ocompiler header functionality, then automatically DJGPP
and RSXNTDJ and any other programming environments which are based on GCC
would automatically support precompiled headers.
