All the code that relies on separating them uses the built-in defines
_WIN32 and _WIN64, or the corresponding machine defines (such as
_M_IX86, for MSVC 32 bit inline assembly).
The object files for this tool aren't built with the /GL flag
(Whole Program Optimization), leading to the following warning
when linking:
/LTCG specified but no code generation required; remove /LTCG from
the link command line to improve linker performance
Enabling link time code generation for the console front end binary
isn't of much use, since this tool in itself isn't performance
critical.
