Dear Sirs: I am a biology researcher working in University. I am compiling one calculation program. I had a trouble for compiling on MacOSX (10.3.9) with gcc 3.3. Error massage is following. "BFunction.cc:615: error: `signbit' undeclared (first use this function)" How can I overcome this? I cannot compile because gcc 3.3 is not included signbit function? Koh-ichiro YOSHIURA
