The warning is enabled by-Wextrafor C and C++. In the original test case above-Wimplicit-fallthroughwill warn about "a = 1;" falling through to "case 2" like this: z.c: In function ‘f’: z.c:7:9: warning: this statement may fall through [-Wimplicit-fallthrough=] a = 1; ~...

@namhyung I found warning messages about -Wimplicit-fallthrough on gcc-7.0.1, on current master branch. The reason is like below. https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html It looks like gcc 7 has added a default warning abo...

When building the 2.2.2 version with GCC 8.3.0, it throws an error as seen in the screenshot below. The only non-patch solution for this was to add-Wno-implicit-fallthroughto the CFLAGS which is less than ideal.
