Dennis Ritchie’s first C compiler (c. 1972) 5 years ago
No, the names are fine and self evident after glancing through K&R for 15 min.
The real mistake in retrospect is that int and long are platform dependent. This is an amazing time sink when writing portable programs.
For some reason C programmers looked down on the exact width integer types for a long time.
The base types should have been exact width from the start, and the cool sounding names like int and long should have been typedefs.
In practice, I consider this a larger problem than the often cited NULL.
