If you are porting a program using Turbo C(BCC) graphics functions to djgpp,
it is *much* simpler to use BCC2GRX library since it provides very good
compatibility with TCC graphics functions. It can be found on omnigate.
(djgpp/pub/bccgrx??.zip)
BCC2GRX needs LIBGRX library. The current versions are BCC2GRX 1.1 and LIBGRX
1.02, but BCC2GRX 1.2 and LIBGRX 1.03 are expected fairly soon.
