C runtimes, for the most part. Things normally distributed as part of

No, sorry. No one agrees with that interpretation.

But almost all of them do not. We need to allow people to not only
write their own GPLed code that use numpy but also to write programs
use GPLed libraries outside of their control.

numpy will never require GPL-incompatible code.
