Re: [boost] [Type_Traits] [remove_bounds]: Wrong workaround for IBM C++ compiler is applied in remove_bounds.hpp

the macro __IBMCPP__ at z/OS is "41130" for my system. The output of xlc++ -qversion is z/OS V1.13 XL C/C++.

For AIX the macro __IBMCPP__ evaluates to "1210" and "xlc++ -qversion" evaluates to:

IBM XL C/C++ for AIX, V12.1 (5765-J02, 5725-C72) Version: 12.01.0000.0004.

So we really have two different compilers for z/OS and AIX, with different versioning and behaviour.

Thanks for all the info! There are a lot of workarounds predicated on __IMBCPP__ in type_traits, can you try search-and-replacing all of them to __xlC__ and then run the tests in libs/type_traits/test with your compiler? Many thanks, John.
