The variable __c is the internal variable used inside the PSTR macro.
This variable must be declared "const", which has recently been
committed to the tree:

        Fix for bug #32988.
        * include/avr/pgmspace.h: Add const keyword to PSTR definition.
        * NEWS: Add to fixed bug list.

Are you perchance accidentally using an outdated version of the
<avr/pgmspace.h> header file (e.g. an installed old version rather
than the in-tree new one)?
