I notice that there are flags in your compile that do not appear in mine: -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Werr= or I don't see any warnings in my build, either. My build is using gcc-4.1.2 (on CentOS 5.9) as a build compiler. My guess is that this is the cause of the differences. I'll upgrade to building with a more recent version of gcc and investigate this failure, but I won't be able to look at this for about two weeks. --=20 Michael Eager eager@eagercon.com 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077
