I'm primarily interested in what will be the solution to the problem? Would one of these be renamed, and which one, or both? Once it will be decided, an appropriate patch will be a matter of fifteen minutes. As to searching for duplicates, the following script seems to find them (all?): include $ (for f in avr/io?*.h ; do \ cpp -I. -D__ASSEMBLER__ \ <(echo "#define _AVR_IO_H_" ; \ echo "#include \"${f}\"") > /dev/null ; \ done) 2>&1 In file included from /dev/fd/63:2: ./avr/io90pwm316.h:912:1: warning: "PSYNC1" redefined ./avr/io90pwm316.h:911:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/io90pwm3b.h:982:1: warning: "PSYNC1" redefined ./avr/io90pwm3b.h:981:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iom1284p.h:950:1: warning: "UBRR0" redefined ./avr/iom1284p.h:947:1: warning: this is the location of the previous definition ./avr/iom1284p.h:1005:1: warning: "UBRR1" redefined ./avr/iom1284p.h:951:1: warning: this is the location of the previous definition ./avr/iom1284p.h:1009:1: warning: "UBRR1" redefined ./avr/iom1284p.h:1005:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iom168.h:72:1: warning: "SELFPRGEN" redefined In file included from ./avr/iom168.h:36, from /dev/fd/63:2: ./avr/iomx8.h:315:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iom168p.h:746:1: warning: "UBRR0" redefined ./avr/iom168p.h:743:1: warning: this is the location of the previous definition ./avr/iom168p.h:840:1: warning: "SELFPRGEN" redefined ./avr/iom168p.h:333:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iom328p.h:747:1: warning: "UBRR0" redefined ./avr/iom328p.h:744:1: warning: this is the location of the previous definition ./avr/iom328p.h:841:1: warning: "SELFPRGEN" redefined ./avr/iom328p.h:334:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iom48p.h:744:1: warning: "UBRR0" redefined ./avr/iom48p.h:741:1: warning: this is the location of the previous definition ./avr/iom48p.h:838:1: warning: "SELFPRGEN" redefined ./avr/iom48p.h:331:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iom88.h:72:1: warning: "SELFPRGEN" redefined In file included from ./avr/iom88.h:36, from /dev/fd/63:2: ./avr/iomx8.h:315:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iom88p.h:746:1: warning: "UBRR0" redefined ./avr/iom88p.h:743:1: warning: this is the location of the previous definition ./avr/iom88p.h:840:1: warning: "SELFPRGEN" redefined ./avr/iom88p.h:333:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iotn13.h:349:1: warning: "SPMEN" redefined ./avr/iotn13.h:245:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iotn2313.h:619:1: warning: "SELFPRGEN" redefined ./avr/iotn2313.h:457:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iotn48.h:755:1: warning: "SELFPRGEN" redefined ./avr/iotn48.h:357:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iotn88.h:743:1: warning: "SELFPRGEN" redefined ./avr/iotn88.h:348:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iousb162.h:53:1: warning: "CKSEL0" redefined In file included from ./avr/iousb162.h:38, from /dev/fd/63:2: ./avr/iousbxx2.h:509:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iousb162.h:54:1: warning: "CKSEL1" redefined In file included from ./avr/iousb162.h:38, from /dev/fd/63:2: ./avr/iousbxx2.h:518:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iousb82.h:53:1: warning: "CKSEL0" redefined In file included from ./avr/iousb82.h:38, from /dev/fd/63:2: ./avr/iousbxx2.h:509:1: warning: this is the location of the previous definition In file included from /dev/fd/63:2: ./avr/iousb82.h:54:1: warning: "CKSEL1" redefined In file included from ./avr/iousb82.h:38, from /dev/fd/63:2: ./avr/iousbxx2.h:518:1: warning: this is the location of the previous definition include $ I'm not sure there're no false positives in the above output.
