Fehlermeldung im AVR-Studio 4

Hallo,

ich habe vor dieses -> http://flosserver.dyndns.org/Sternenhimmel.php
Projekt nachzubauen, dazu habe ich mir das Programm von den Jungs 
schicken lassen. Wenn ich es im AVR Studio builden möchte kommt immer 
folgene Fehlermeldungen.

../irmp.c:830:31: error: variable 'nec_param' must be const in order to 
be put into read-only section by means of '__attribute__((progmem))'
../irmp.c:851:31: error: variable 'nec_rep_param' must be const in order 
to be put into read-only section by means of '__attribute__((progmem))'

to be put into read-only section by means of '__attribute__((progmem))'

../irmp.c:1126:31: error: variable 'grundig_param' must be const in 
order to be put into read-only section by means of 
'__attribute__((progmem))'


Darauf hin hab ich ihn angeschrieben. Leider weis er auch nix genaueres 
über diese Fehlermeldung. Kann mit von euch evtl. jemand sagen was das 
Problem sein könnte?
