Subject: gcc hang, LIBGRX/BCC2GRX: a good news

Hi, everybody.

Despite the gcc hang problem, I'v just successfully ported my program from BCC
to djgpp/gcc. (I compiled without optimizaion.  Otherwise gcc hanged.)

My program was intensively using Borland C's BGI graphics functions with a 256
color BGI driver, so I couldn't imagine to port it without using LIBGRX/BCC2GRX
graphics libraries. (Thanks to the authors.) 

The ported program showed better _graphics_ performance than the original BC
compiled program.  This is unexpected since I thought that the BCC2GRX's 
indirect calls to LIBGRX couldn't be so effective, comparing with direct 
video handling (bypassing LIBGRX).  But, it turns out to be fast enough.
(Maybe faster data computations enhanced the overall graphics speed.)
(The reason I ported to djgpp/gcc is to overcome the dos memory limit.
Speed is a by-product.)

Still, I like to hear your comments about gcc hang problem.

Thanks.

Wonkoo.
