Thank you for your reply.
Will try this.
Have also created an Eclipse project to generate libnutarch.a. Including the same sources as in the Nut Makefile. It compiles; will test that also.
Realtime Control Works

Yes you can add selective macros definitions to a GNU makefile by
prefixing the definition with the target name. For example:
avr/dev/ostimer.o: CPFLAGS = $(MCFLAGS) -O0 $(DEFS)
would apply different CPFLAGS settings only when compiling ostimer.o.
