What I forgot to mention - there is likely incompatibilities when
different compilers are used. This is definetly the case when source
files need a C compiler - and I fear that the different run-time
environments of gcc versus xlc (which does not need/link to glibc).

So, how does, e.g., macos account for differences between clang and gcc
compiled executables and modules. Or are both compilers "gnu" oriented?
