My recommendation is to use "#include <msp430.h>" which is MCU-independent
(it will reference a preprocessor definition that results from using -mmcu,
and will include the appropriate header). Others disagree and say you
should include the header specific to the code you're writing (assuming the
code you're writing is specific to a particular MCU).
Either way, using -mmcu isn't an option. The compiler and linker need
information about the target MCU that can't be inferred from an include
file.
