// RUN: %clang_cc1 -Wmissing-variable-declarations -fsyntax-only -verify %s
Add a new warning -Wmissing-variable-declarations, to warn about variables defined without a previous declaration. This is similar to -Wmissing-prototypes, but for variables instead of functions. Patch by Ed Schouten. llvm-svn: 166498
