Configure: fixed type max value detection. The code tried to use suffixes for "long" and "long long" types, but it never worked as intended due to the bug in the shell code. Also, the max value for any 64-bit type other than "long long" on platforms with 32-bit "long" would be incorrect if the bug was fixed. So instead of fixing the bug in the shell code, always use the "int" constant for 32-bit types, and "long long" constant for 64-bit types.
