$ fgrep pgm_read_byte ~/src/avr-libc/include/avr/pgmspace.h
pgm_read_byte_near() or pgm_read_word_near() instead of
pgm_read_byte_far() or pgm_read_word_far() since it is more efficient that
\def pgm_read_byte_near(address_short)
#define pgm_read_byte_near(address_short) __LPM((uint16_t)(address_short))
\def pgm_read_byte_far(address_long)
#define pgm_read_byte_far(address_long) __ELPM((uint32_t)(address_long))
\def pgm_read_byte(address_short)
#define pgm_read_byte(address_short) pgm_read_byte_near(address_short)
So well, I think it's just there.

Never trust an operating system you don't have sources for. ;-)
