MSVC compile error C2051: case expression not constant

[ddengster]

Was trying to compile pt.h and pt_test.c on windows when i hit this compile error.
This line is likely causing the error: https://github.com/zserge/pt/blob/master/pt.h#L91

The error's probably about case LINE: not being compatible with MSVC. Is there a workaround of some sort?

I think the issue you discovered is discussed here. Sounds like you can avoid the compile error by changing a setting in your Visual C++ compiler related to debug information.
