[ros-dev] [ros-diffs] [tfaber] 64749: [PSDK] - Use macro version of RtlUlonglongByteSwap in winternl.h because using the fastcall version causes stack corruption CORE-8632 #resolve

[Timo Kreuzer]

What I really wonder: since the function behaves like cdecl, why does 
wine declare it as fastcall? Or is this also our own hack, because the 
function has fastcall symbols and it's declared as fastcall in wdm.h for 
compilers with _MSC_FULL_VER <= 13009037?
IMO we should remove all traces of it being fastcall and simply declare 
it as cdecl. There is no reason to reproduce MS header bugs.
And we should probably also kill the asm file for it. There is no need 
for it.
