You found a mistake in the code comments that were brought over with this code from Autoconf Archive. Lines 466 through 473 specify the options to be enabled. The option before the '%' character is used to detect which type of compiler we're dealing with. The options(s) after define the options to use when compiling. To answer your specific question about GCC, only '-Wall' gets used to compile. Best regards, Dale
