As I noted in earlier email, msp430-libc has new functionality that has increased the size of some programs built with newer versions of mspgcc. There are helpful hints about reducing program size in the thread beginning at:
http://www.mail-archive.com/mspgcc-users@lists.sourceforge.net/msg10968.html If you update to mspgcc 20120618 and use flags: -mmemory-model=medium -ffunction-sections -fdata-sections -Wl,-gc-sections the problems may be resolved. This would only work if your target chip supports the CPUX extensions and has memory above 64 kiB; if it's just a slightly larger sub-64 kiB MCU, then you'll want to try things like disabling 64-bit and maybe 32-bit printf support in msp430-libc. See the referenced thread above for information.
