That is a beautiful theory in an ideal world, but in the real world, implementations have bugs, and sometimes we need to workaround these bugs. (e.g. the FD* issue reported by Martin Galvan). So when writing code that should work with different implementations, these macros are needed to apply workarounds for implementation-specific bugs. That's why all the rest of the C lib implementations do provide an identifying macro, something that I think musl should also do, IMVHO.

One guess, that’s who? Who’d never, ever start an argument? Who never shows a bit of temperament? Who's never wrong but always right? Who'd never dream of starting a fight?
