[GEM-dev] compiling GEM for Win with gcc

[Thoralf Schulze]

Hi there,

I'm still struggling to get the cvs version of GEM
compiled for Win with gcc (dev-c++). DSgrabber.cpp
includes some microsoft header files, with winnt.h
being one of them. Unfortunately, this one
incorporates some inline assembler, like this:

#if _MSC_VER >= 1200
#pragma warning(push)
#endif
#pragma warning(disable:4035 4793)               //
re-enable below

__inline ULONGLONG
NTAPI
Int64ShllMod32 (
    ULONGLONG Value,
    DWORD ShiftCount
    )
{
    __asm    {
        mov     ecx, ShiftCount
        mov     eax, dword ptr [Value]
        mov     edx, dword ptr [Value+4]
        shld    edx, eax, cl
        shl     eax, cl
        }
}

This seems to be the Intel flavour of assembler
notation, while gcc defaults to the at&t one.
Unfortunately, -masm=intel doesn't help:
