Hi Nick,
Thanks for the suggestion. I just tried that, but it unfortunately it
doesn't seem to have any effect.
$ msp430-elf-gcc -mmcu=msp430g2231 -Os -static -Wall -Wextra simple.c -o
simple.elf -Wl,-gc-sections
/usr/lib/gcc/msp430-elf/4.9.0/../../../../msp430-elf/bin/ld: simple.elf
section `.bss' will not fit in region `RAM'
/usr/lib/gcc/msp430-elf/4.9.0/../../../../msp430-elf/bin/ld: region `RAM'
overflowed by 14 bytes
collect2: error: ld returned 1 exit status
