The reason I was using -nostdlib was so that I could reduce the number of errors I was getting. My first thought was that newlib had not built correctly so I was trying to eliminate all possible sources of problems. With your advice I see now that that opens a whole new can of worms. In the end, after a lot of tears, I found that with mips-gcc and the standard cross build, you need to override the default linker script with one of the debug stub monitor scripts, (-T). As I'm not using a remote debug stub, I chose the nullmon.ld script and Bob's your auntie my code compiled! I am still to check the executable is valid! Thanks for your help...
