           Summary: -Wempty-body is enabled by default
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

gcc hasn't -Wempty-body enabled by default (only if explicit declared or
-Wextra), but clang has. So clang produces warnings like:

Wempty-body.c:2:8: warning: if statement has empty body [-Wempty-body]
  if(1);

while gcc compiles code silently.

It prevents using clang as drop-in replacement for gcc if project has -Werror
in CFLAGS.
