Hi,

I'm trying to convert the C++ source code for my 3d engine from 
Watcom C/C++ 10.6 to DJGPP2 and I'm having some problems with 
inline asm pragmas... The AT&T syntax should be no problem but
I don't know how to pass parameters and return values etc...
If someone could translate the short pragmas below to DJGPP inline 
asm for me I'd be grateful... (Please reply by email as well...)

/Lars Andersson
