compiling using msvc

[totaam]

For compiling with MSVC on win32, you have to remove the extra_compile_args, or better still replace it with one suited for MSVC like this one:

extra_compile_args=["/Ot", "/Wall", "/DLZ4_VERSION=\"r119\""]

More information on those flags can be found here:

(not sure how you would go about detecting which compiler is going to be used by distutils - I guess checking for environment variables like VCINSTALLDIR is a good bet? or maybe checking if CL.exe is on the PATH but GCC isn't?)

I would try:
from distutils import ccompiler
if ccompiler.get_default_compiler() == "msvc":

But that wasn't enough for vs2008. Still need stdint.h.

If this library is still maintained it's easy to add AppVeyor configuration to run lz4 tests on Windows to prevent issues like this.
