To generate Visual Studio files in vs2015 directory, run: premake5 vs2015

I'm using premake5 alpha9 from http://premake.github.io/download.html#v5
(premake4 won't work, it doesn't support VS 2013+)

Note about nasm: when providing "-I foo/bar/" flag to nasm.exe, it must be
"foo/bar/" and not just "foo/bar".

Reference for warnings:
 4018 - signed/unsigned mismatch
 4057 - function X differs in indirection to slightly different base types
 4100 - unreferenced formal parameter
 4127 - conditional expression is constant
 4131 - uses old-style declarator
 4189 - local variable is initialized but not referenced
 4204 - non-standard extension: non-constant aggregate initializer
 4206 - non-standard extension: translation unit is empty
 4244 - 64bit, conversion with possible loss of data
 4267 - 64bit, conversion with possible loss of data
 4302 - 64bit, type caset truncation
 4311 - 64bit, type cast pointer truncation
 4312 - 64bit, conversion to X of greater size
 4324 - 64bit, structure was padded
 4458 - declaraion of X hides class member
 4530 - exception mismatch
 4702 - unreachable code
 4706 - assignment within conditional expression
 4800 - forcing value to bool (performance warning)
 4819 - The file contains a character that cannot be represented in the current code page
 4838 - conversion from X to Y requires a narrowing conversion
 4996 - POSIX name deprecated

Prefast:
 28125 - function X must be called in try/except (InitializeCriticalSection)
 28252 - Inconsistent annotaion
 28253 - Inconsistent annotaion
