I noticed that with the suggested fix applied in configurations where
'val' can't exceed a long on the positive side GCC (trunk from some time
ago) is complaining emitting the following warning:

comp.c:1174:22: warning: logical ‘or’ of collectively exhaustive tests is 
always true [-Wlogical-op]
 1174 |   if (val > LONG_MAX || val < LONG_MIN)
      |                      ^~

Not sure what's the best way to silence it or if we want to revert to
the previous formulation.
