Non portable 'warning' preprocessor command

[tetsuhaut]

In the file include/stlab/concurrency/config.hpp we find some #warning preprocessor commands, which are unknown in MS visual studio and trigger a compilation error.
You may want to use something like

#ifdef _MSC_VER
#  pragma NOTE(my warning here)
#else
#  warning(my warning here)
#endif

instead.

Which VS version are you using? I don't see this with VS2017 and VS2019.
(VS 2015 is not supported any more.)
Edit: I see that this happens with C++latest

Thanks for spotting and reporting this

This happens in Microsoft Visual Studio Community 2019 Version 16.8.4. I suspect it would happen in any version, as some Stackoverflow issues (https://stackoverflow.com/questions/471935/user-warnings-on-msvc-and-gcc) let it guess.

Fixed in 1.5.6
