/MP cl.exe build with multiple processes
/utf-8 set source and execution character sets to UTF-8
/bigobj increase # of sections in object files
/permissive- enforce more standards compliant behavior
/sdl- disable additional security checks
/FC full path in compiler messages
/Gd __cdecl
/GS- disable buffer security checks
/Gy Enable Function-Level Linking
/GF Eliminate Duplicate Strings
/wd4068 unknown pragma
/wd4146 negate unsigned
/wd4819 codepage?
/wd6237 short-circuit eval
/wd6319 a, b: unused a
/wd26444 unnamed objects
/wd26451 overflow
/wd26495 uninitialized member
/WX- (do not) Treat Warnings as Errors
/W1 Warning Level
/TP every file is a C++ file
/Zc:forScope Force Conformance in for Loop Scope
/Zc:inline Remove unreferenced COMDAT
/Zc:wchar_t wchar_t Is Native Type
Additional C++ flags used by RelWithDebInfo builds:
/Ob1 Inline Function Expansion (1 = only when marked as such)
/Oi Generate Intrinsic Functions
Linker flags used by all builds:
/OPT:REF remove unreferenced COMDATs
/OPT:ICF folds identical COMDATs
/DYNAMICBASE does this app really need ASLR ?
/NXCOMPAT same as above
No need to force /TLBID:1 because is default
