i'm some kind of frustrated about the AVR assembler 1.30...
here some of the "bugs" i think you should know:
+no macros in macros allowed
+no chance to use jumppositions in a macro (just once)
|-no work around with .DW x,x,x -> also not allowed in amcros
+and sometimes i just wonder about the behavior of .EQU constants
this are not realy bugs... but frustrating...
