Early Roguelike Collection: arogue7/list.c annotate

annotate arogue7/list.c @ 165:2d94c32a709e

arogue7: comment out a problematic message. This line causes a segfault on x64. I suspect one of the char* arguments to msg() is being corrupted. But gdb doesn't make it easy to debug variadic functions, and the crash doesn't occur when running under valgrind. So the message is being removed until I can discover the root of the problem.
