add support for wider type in switch-case
Currently the different cases of a switch-statement, or more
exactly the 'struct multijmp' that hold the value of these cases
excepted only value of 'int' type. Trying to use a wider value
results in the value being truncated but any integer value should
be valid.
Fix this by unsigned 'long long' to hold these values.
