After clarification about the C standard, POSIX, and implementations:
The C standard allows errno-setting, and it's (unfortunately for optimization) even
more clearly stated in the newer additions to the standards.
We can leave these functions as always constant ('c') because they don't
actually do any math and therefore won't set errno:
