Nothing is stopping the rest of the world from enjoying 32-bit externs.
A little (very little) information theory will show that this cannot
be guaranteed by any amount of trickery in a 6-character extern
environment, if one does not have control over the linker etc.
The proposed ANS for C does NOT repeat NOT prohibit implementations
from supporting more than 6 monocase characters of significance in
external identifiers.

It's already ignored, and already causes problems.
