“That we even need those aliases is usually a case of bad automake / 
autoconf / bad feature detection”

These are for ABI compatibility, not API compatibility. Nobody using 
glibc uses these symbols intentionally, they are renamed and aliased by 
the library. Last I checked, musl is shockingly close to ABI 
compatibility with glibc, and like it or not, that's a valuable feature. 
If you don't like the “bloat” of it, you'll have to dig out a lot of the 
existing aliases too.

With valediction,
