[Bug libc/2926] New: assert macro contains unreachable code

["Jerry dot James at usu dot edu" <sourceware-bugzilla at sourceware dot org>]

When compiling with gcc and the -Wunreachable-code flag, gcc warns about every
use of the assert macro from <assert.h>.  This was reported as a gcc bug (see
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22414), but the gcc team declared it
to be a glibc bug.  Indeed, moving __ASSERT_VOID_CAST inward to apply to the two
instances of 0 in assert and assert_perror leaves the assertions working
correctly and eliminates the warnings for me.  I don't see a place to include a
patch on this page, so I'll submit the bug and hope I can attach a patch later.
