Hi, I'm working on incorporating FLAC into an audio player I wrote, and I've come across a slight problem. The compiler I use doesn't have 64-bit integer support (Watcom v10.6). I have compiled it with gcc, but I need to link with other libraries that are not compatible with gcc's stack calling conventions, so I can't use gcc and must use Watcom. A few questions: 1) What are the 64-bit integers used for in FLAC? 2) Would I be able to substitute the 64-bit integer uses to 32-bit values, and what problems will this cause? 3) If 64-bit integers are necessary, does anybody have a 64-bit library (source) that might work? Thanks in advance for any help! Ron
