I am not too sure which C compiler defines a data type of __int8 (has to be
windows... ).

Try this

typedef __int8 char;
typedef __int16 short int;
typedef __int32 long int;

stick this in a header file that's included by all source files that use this
notation.  You will now have pseudo-variable types with these names.
Or just do what most real programmers would, and use unsigned char.  The
typedefs are handy for portability across different sized architechtures,
though.
