For me, that didn't really work, either because the C library I used (I
think it was newlib) also references write() when using vsprintf()...
The solution for that was defining write() (and all the other functions
referenced by the printf functions I don't need) myself (like "int
write(...) { return 0;}"), to fool the linker: they don't get called
anyway.
