the list of unimplemented items in /sys/src/cmd/cc/c99* is:

9, 19. Hexdecimal floating point constants.
11. _Complex, _Imaginary, _Bool
14. Variable arrays in parameter lists.
33. Variable-length arrays
34. goto restrictions for variable-length arrays
18. Notation for universal characters \uXXXX
25. Division and mod truncate toward zero.
26. _Bool, float _Complex, double _Complex, long double _Complex

i can think of something else that's not been noticed,
but what other things have you found?
