To see more details look in the avr-libc-users-manual and/or the
pgmspace.h include file.

To get a version of avr-libc with far support you have to edit
pgmspace.h and redefine the macro PRG_RDB
#define PRG_RDB(addr)   pgm_read_byte_far(addr)
and then don't forget to make and install it.

Please note that the PRG_RDB() macro is deprecated and should not be used. It is best to use pgm_read_byte(), pgm_read_byte_near(), or pgm_read_byte_far().
