Thanks for this insight. DMD uses the C runtime's `strto{f,d}` to check for
over/underflows of float/double literals (in
`Port.isFloat{32,64}LiteralOutOfRange()`). So an Apple libc change might indeed
be the culprit. - LDC isn't affected, it uses LLVM functionality to parse
floating-point literals.
