It is used ( However 386 is not really supported any more for DJGPP
for rather long time. I do not have corresponding hardware to test on 386 already for a long time
so I did not do any testing on 386 when I built recent GCC versions for DJGPP for DJ FTP server
(last is gcc-4.7.2). As far as I remember read in mailing list 386 support no more work (at least
C++ standard library). So I guess deprecating 386 could be not too large loss.
