A List_Name_Count variable is initialized with zero, then incremented
and decremented in a stack-like manner, so it should never become
negative.
This gives us extra confidence, but otherwise the behaviour is not
affected.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* pprint.adb (List_Name_Count): Change type from Integer to
Natural.
