Bluez and bluetooth

Hi,
     I pulled over the libbluetooth-dev package and I can compile a 
simple exercise and run it on my Mint 13 PC using gcc.

     Moving onto msp430-gcc I get
msp430-gcc -Os -Wall -g -mmcu=msp430f5438a -c main.c
main.c:4:20: fatal error: unistd.h: No such file or directory
compilation terminated.
make: *** [main.o] Error 1

I guess it found stdio.h
locate -i unistd.h      //found lots of possibilities.
/usr/include/unistd.h
/usr/include/asm-generic/unistd.h
/usr/include/bsd/unistd.h
/usr/include/linux/unistd.h

     I guess I need to tell msp430-gcc which one to use and obviously I 
need as a minimum msp430 compiled libraries to link with.  Do I have to 
generate these from sources or are these bluetooth libs in the 
msp430-gcc system waiting for me to pull over?  Any pointers would be 
greatly appreciated.  Regards Ian.
