* Build: Catch incorrect format specifiers with /we4777 and fix issues.
Most of these are using %d for a DWORD when it should be %ld.
* More compilation fixes
@GladYouLikeIt described the bug in the issue:
> Extend.cpp is built into extend64.dll for x64, and extend86.dll for x86,
> but the code in samples\findfunc\extend.cpp references the dll without
> specifying the DETOURS_BITS in the dll name. DetourFindFunction fails
> at runtime because of this.
@ohuseyinoglu noted the same bug in SymTest.cpp as well.
