It now appends the 'U' suffix only to literals that are used in an unsigned

L/LL suffixes for integers that might exceed the int/long limits.
Why not just keep it simple, append no suffixes and let the C/C++
compiler deal with it? No heuristics needed.
More concretely, I would handle this as follows:
* do not use any L or U suffix
* write all DEF constants as hexadecimal in the source code
This way, the C/C++ compiler will determine the integral type. It will
use the first type in the following list which can represent the number:
- int
- unsigned int
- long
- unsigned long
- long long
- unsigned long long
The reason for the *hexadecimal* constants is that the unsigned types
are not tried for decimal constants.
