Is there an equivalent to the Sun Compiler's -mt option

For the compiler itself, you don't need a flag. It will work just fine
- single-threaded or not. For the system libraries, you can use the
-pthreads option. This will add -D_REENTRANT -D_PTHREADS to the
preprocessor predefines, and adds -lpthread to the linker command
line.

Please note that you should have specified --enable-threads when you
built the compiler, to get thread-safe exception handling.
