I have exactly the same problem.
It would be handy to have a macro to store a 17 bit full pointer into a long
variable and another macro
PRG_RDB_EX which takes such a pointer and returns the FLASH byte at that
position.
This would allow users of atmega103 and 128 to use more than 64k as data
memory.
This macro would need to use the ELPM instruction and use more cyles and
therefore this should only be an option - not the general case.
