Since there are at least two other GCC ports (GCC/2 and EMX) that I am aware
of that run in native OS/2, there is no reason to even think about this.  The
OS/2 APIs are so much different that the libraries would be a complete
rewrite; and then so would the loader/extender/linker-obj interface depending
on how you wanted to accomplish that.

Because I tri-boot all the time between DOS, OS/2 and NT, I get tired of
having different binaries for each op system.  Using DJGPP apps everywhere
is easiest for me.  That way when I need a new version I only have to build
it ONCE too (and 1/3 the disk space...).

I am looking at extending DJGPP to be able to write Windows type apps for
Win32s or Chicago (or NT), but the pace of that is glacial :-(
