MSVC build errors

[mkatliar]

The project does not build with MSVC. Reasons:

1. gcc-specific compiler options are used without checking actual compiler in CMakeLists.txt
2. <sys/time.h> is absent on Windows
3. Missing const specifiers in example2_affine.c
4. Misplaced/missing "#ifdef **cplusplus extern "C""
5. __MEASURE_TIMINGS** explicitly defined in qp/types.h, QPDUNES_MEASURE_TIMINGS ignored.

Support for Windows is only experimental, but any improvement on this end is of course very much appreciated

[mkatliar]

I have fixed the build errors and committed them to the msvc-build-fix.

👍 Very good. Does make test work on Windows now?

There is no make test on Windows, but ctest -C Debug outputs this:

The test that fail on Windows but do not fail on Linux fail because use of uninitialized values is detected.
