[dcb@dhcppc0 avr]$ fgrep str_prefix_p gen-avr-mmcu-specs.c str_prefix_p (const char *str, const char *prefix) $ I show the version from today's trunk revision 261132. Your version seems to be revision 256169, some 4,963 revisions ago. I suggest you update to trunk and check again. Perhaps you are using a non-trunk branch ?
