Fix the clang build
Simon pointed out that gdb would not build with clang, due to the addition of -Wimplicit-fallthrough. This patch fixes the problem by using -Wimplicit-fallthrough=3 -- this does not work with clang, bypassing the issue. Tested by rebuilding with both gcc and clang; and also by verifying that -Wimplicit-fallthrough=3 is used in the gcc build. I will file a follow-up bug to convert the fall-through comments to a form that can be used by both clang and gcc. gdb/ChangeLog 2018-05-10 Tom Tromey <tom@tromey.com> * configure: Rebuild. * warning.m4 (AM_GDB_WARNINGS): Use -Wimplicit-fallthrough=3. gdb/gdbserver/ChangeLog 2018-05-10 Tom Tromey <tom@tromey.com> * configure: Rebuild.
