None of the 64-bit compilers support inline assembly anymore. The VC++ team thinks that providing "intrinsic" is good enough: http://msdn2.microsoft.com/en-us/library/26td21ds.aspx I think a more realistic option would be to move the assembly code to a separate file and compile it using ml64.exe (a 64-bit version of good old MASM), also included in the 64-bit Platform SDK at this location: C:\Program Files\Microsoft Platform SDK\Bin\win64\x86\AMD64\ml64.exe I have no idea what else might be involved though; I haven't looked at the assembly level details of calling conventions in 64-bit mode, and if anything needs to be adjusted there as well.
