Yes, I think it should be conditional silenced for musl, otherwise it has blocked \
following builds, such as for main.exe and runtest.exe. So I think it is an issue, \
right?

this is expected:
posix requires these macros but musl does not define them.
in practice they are unlikely to be needed so i guess
these should be silenced in some way.
