| |
-Wimplicit-fallthrough=5 was under cc-option because it was only available in GCC 7.x and newer so the build is now broken for GCC 5.x and 6.x:
gcc: error: unrecognized command line option '-Wimplicit-fallthrough=5'; did you mean '-Wno-fallthrough'?
Fix this by moving -Wimplicit-fallthrough=5 under cc-option.
