- djgpp 1.08 is derived from gcc 2.2.2

- The trident driver in Csaba's excellent LIBGRX contrib package contains
- a similiar patch... I haven't checked if its identical.
-
- Also, I noticed that bank switching fails right after you do a printf
- to a graphics mode.. the next few graphics writes ALWAYS end up in the
- first bank. I haven't gotten around to reproducing this in small code, so
- I don't know if its a go32 problem or a board problem. My first guess
- would be to blame the board. We all know that Trident == Bug_ridden_lazy_DOG!
-
- In any case, at least when my app spews error messages to stdout I know where
- in the picture the problem is, since it ends up in the top part of the
- screen - MUST be a feature :-)
-
- In addition, I've been having problems with the 1024x768 mode too. Nobody
- but me has seen them (btw. I have a 8900B). Oh lord / won't ya buy me / a
- local bus s3...
