[3d4m-volodymyr]

Im trying to compile POCO library.

Macros listed here:
http://www.cplusplus.com/reference/cfenv/

File in project https://github.com/emscripten-core/emscripten/blob/main/system/lib/libcxx/include/cfenv

Can those macroses be added to header?

I think this merge broke
https://github.com/emscripten-core/emscripten/pull/11087/files

[kripken]

Based on the discussion there, I think this must be changed in the source code of that project. It is ok for those macros to not be defined, and I think Emscripten is correct to not define them.

[3d4m-volodymyr]

I thought it's part of C++11 standard. Can we trust this source ?

[3d4m-volodymyr]

Ok, does not look like a standard.

Sorry, I should been spend more time reading thread. Now I got the idea. :)
