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...)

"cdq "\
"shld edx, eax, 20 "\
"sal eax, 20 "\
