GCC tells me that I am redefining a macro. I have searched my code several times, and no-where is this macro explicitly redefined. I've seen this sort of error before, with the culprit being a misplaced brace character or some such thing. Any suggestions for more speedily tracking this problem down? Manually searching the code will likely turn it up, but there's a lot to search through, and several hours later I haven't found it yet. Thanks!
