A conforming program could be said to run correctly under a
non-conforming C implementation if some test suite fails to find
anything wrong with the program.

For example it's not uncommon to see programs that use
1<<(sizeof(int)*CHAR_BIT-1) instead of INT_MIN. Any such program would
be highly unlikely to run correctly on the 36-bit ones complement C
