Hello.

I heard that DJGPP would produce faster code than Watcom, so I'm trying to
port my Watcom sources to DJGPP. I've encountered a few problems with
this.

----------------

1. When using Watcom I declared my interrupt routines as follows :

void (__interrupt __far __cdecl Introutine)()

This won't work with DJGPP, I get a parse error from the compiler.

*** How do I overcome this problem ?

------------------

2. In Watcom I used pragmas for inline assembly functions.

#pragma aux func =3D  \
 "shl eax,1"        \
 parm caller [eax]  \
 value [eax];

Doesn't really do much... Just an example.

* parm caller [eax] show where to put the input parameter.
* value [eax] shows where it will be returned.

*** How do I declare the in & out parameters in DJGPP's assembler AS?

-------------

Thanks.
