-
- Yes, GCC 2.2 has been ported to the ST. I thought it was already on
- atari.archive, I guess not. I can put a copy up in the next couple of
- days.

-
- The libraries that come with GCC will support the FPU.

-
- Interesting. If ".TGA" means what I think (TARGA) then you want to
- convert some 24-bit true-color images into ST 640x400 monochrome?
- Yeehah.
-
- The PC version of FractInt reads and writes TARGA files. You can
- probably use it to read them and save as GIFs, which you can then
- convert to some other format easily enough.
-
- What program do you use on the PC to display these TGA files, anyway?
