The libstdc++ testsuite now supports compilation with the -fno-exceptions flag. The testsuite_allocator.h header was modified to use __try and __catch instead of try and catch blocks, which are unavailable when exceptions are disabled. This allows the testsuite to run correctly in environments where exception handling is not enabled.
