Compiler warnings when compiling EEPROM.h

[nickgammon]

Under 1.6.4 of the IDE (and reportedly under nightly builds as well) compiling an EEPROM example gives this warning:

In file included from eeprom_get.ino:18:0:
/home/nick/Development/arduino-1.6.4/hardware/arduino/avr/libraries/EEPROM/EEPROM.h:43:30: warning: type qualifiers ignored on function return type [-Wignored-qualifiers]
     operator const uint8_t() const       { return **this; }
                              ^
/home/nick/Development/arduino-1.6.4/hardware/arduino/avr/libraries/EEPROM/EEPROM.h:92:26: warning: type qualifiers ignored on function return type [-Wignored-qualifiers]
     operator const int() const          { return index; }
                          ^

To fix, remove the first const from both of those lines.

Cheers, in the update proposal I have in the works, all the warnings are fixed.

Once all the changes are pushed, I'll link here and add a post the dev mailing list. 👍

Any update on this?

[Chris--A]

Yeah, I have the updated files ready, I'll do up a PR after work tomorrow.

Bump - problem is still there in 1.8.0. Need to compile with "All" warnings on to see it.

[Chris--A]

This has been fixed and added to the next proposal (Chris--A@acbd8bc) here

@Chris--A I can't seem to find the pull request.

It looks like this is still present in 1.8.5

Any news on removing the two const qualifiers?

Do you think making a PR would help with this 2½ years old trivial fix ?

[nickgammon]

It can't make things any slower. :)

I'm closing this in favor of arduino/ArduinoCore-avr#36 which describes the same issue, but is in the (by now) right repository (and has a PR with a fix).
