In the same word open64 couldn't link because of that, but isn't much
important since they have to fix lots before having it being even
interesting for general consumption.

inline vs pure asm (and foreign assembler) isn't much my point anyway.

It's more proper intrinsics in C vs asm, as I stated before stand alone
asm and inline asm is a good workaround and a quite inflexible optimization.
