can't compile gsl_tests with VS2022: warning C4067: unexpected tokens following preprocessor directive

[juandent]

Just cloned gsl and tried compiling project gsl_tests which has /WX option and the error occurs at:

#if defined(__clang__) && __has_warning("-Wunsafe-buffer-usage")

As far as I know, Visual Studio does not define clang so it should short circuit before testing __has_warning! I understand VS does not define __has_warning correct?

I compiled using /std:c++20 but I think this does not matter

I have fixed this issue in PR1157

I fixed that already in #1149 in March - only waiting for it to be merged. I don't know if two PRs with the same fix help.

Ohh, I have not noticed your fix, it just has bitten me recently so I fixed it. Seeing that your PR is not merged either I am afraid that it does not matter as there is not much maintenance going on.
