1GCC7 adds -Wimplicit-fallthrough to warn when a switch case falls through,
2however this causes warnings (which are promoted to errors) with the elfutils
3patches from Debian for mips and parisc, which use fallthrough's by design.
4
5Explicitly mark the intentional fallthrough switch cases with a comment to
6disable the warnings where the fallthrough behaviour is desired.
