540 cc-fullversion
541 cc-fullversion is useful when the exact version of gcc is needed.
542 One typical use-case is when a specific GCC version is broken.
543 cc-fullversion points out a more specific version than cc-version does.
544
545 Example:
546 #arch/powerpc/Makefile
547 $(Q)if test "$(cc-fullversion)" = "040200" ; then \
548 echo -n '*** GCC-4.2.0 cannot compile the 64-bit powerpc ' ; \
549 false ; \
