Building hexcurse with gcc-7.1.0-r1 fails with a variety of otherwise non-fatal compilation errors due to the inclusion of -Werror in the build flags. eg, acceptch.c: In function ‘wacceptch’: acceptch.c:299:19: error: this statement may fall through [-Werror=implicit-fallthrough=] currentLine -= (2*MAXY); ~~~~~~~~~~~~^~~~~~~~~~~ acceptch.c:301:2: note: here case CTRL_AND('d'): ^~~~ Compilation should ideally be successful in the face of these warnings, else they should be converted to -Werror=foo rather than the blanket error flag.
