55bdee9af3 libstdc++-v3/libsupc++/eh_call.cc: Avoid "set but not used" warning 
When building with -fno-exceptions, bad_exception_allowed is set but
not used, causing a warning during the build.

This patch adds __attribute__((unused)) to avoid it.

fb00a9fc39 libstdc++-v3/libsupc++/eh_call.cc: Avoid warning with -fno-exceptions. 
When building with -fno-exceptions, __throw_exception_again expands to
nothing, causing a "suggest braces around empty body in an 'if'
statement" warning.

This patch adds braces, like what was done in eh_personality.cc in svn
r193295 (git g:54ba39f599fc2f3d59fd3cd828a301ce9b731a20)
