Encountered already one :(
1. I don't think we can claim "good" /W4 compile on VS2015, as it even
complains on /W3 (the throwing destructor issue we already discussed)
2. If compiling with /W4 we get a load of C4100s warning about
"unreferenced formal parameters" and some C4505s "unused local
variable" and some "conditional expression is constant" and we get
lots of these warnings.
3. Linking to Crypto++ yields some issues breaking the ability to use it.
More specifically the below demo program lets VS2015's linker fail.
(assuming you put the RC into "cryptopp" in the sln's directory and run
the build of Crypto++ before)
Broken Modes: Release|x64, Debug|x64
One may need to replace "Win32" by "x86" depending on the locale.
I've no idea on how to fix the resulting linker errors.
