"$^" is a (GNU?) extension (so it probably will work on any OS where GNU make is available). POSIX make[1] only knows @%?<* as internal macros, and "$<" fits best.

This will cause a lot of "undefined reference to..." errors. I currently don't have my GNU/Linux machine at hand so I cannot test whether "$^" would cause any problems there. (Though I doubt it).
$(AR) $@ $(CORE_O) $(LIB_O) should work in the default case and for MinGW as well.
