Sudden compiler errors with Hackvision

Up until a couple of days ago I was able to compile and upload files to my Hackvision board. Now whenever I compile, I'm getting these errors I've never seen and I have no clue what happened. Was the syntax suddenly changed or is there something messed up with the compiler?

prog_char is the old way of using progmem - it's not supported by modern versions of the GCC AVR toolchain as used by 1.6.x; You need to change the library (or your code, wherever the prog_char declarations are) to correctly declare those (I think char PROGMEM instead of prog_char).
