Just to int temp_.

Then the {} parenthesis will be no more needed in NutEnterCritical, NutExitCritical because there will be no more need to declare such a local variable.
There are functions with NutEnter / NutExit pairs , e.g. UsartResetBuffer() in dev/usart.c.

Are you sure all compilers can optimize existing code?
