+Subject: [PATCH] Add explicit breaks to avoid implicit passthrough.
+
+commit 54666237455273e147eadb1904d261ed7624a8b6 from upstream
+git://github.com/unbit/uwsgi.git
+
+-Werror=implicit-fallthrough was added in gcc 7.1, which will
+throw a compile error if a switch has an implicit passthrough.
+
+Seeing as how this switch doesn't appear to depend on passthrough to
+function correctly, I've added explicit breaks to the switch.
+
+From https://gcc.gnu.org/gcc-7/changes.html:
+
+-Wimplicit-fallthrough warns when a switch case falls through. This
+warning has five different levels. The compiler is able to parse a wide
+range of fallthrough comments, depending on the level. It also handles
+control-flow statements, such as ifs. It's possible to suppress the
+warning by either adding a fallthrough comment, or by using a null
+statement: __attribute__ ((fallthrough)); (C, C++), or [[fallthrough]];
+(C++17), or [[gnu::fallthrough]]; (C++11/C++14). This warning is enabled
+by -Wextra.
