Hello, I've found and fixed a problem where pgcc -E translates its input to contain extra spaces. Since config.guess expects the preprocessor output to be a well formed shell variable assignment, I've added some sed code to ensure this. Please consider the attached patch for inclusion in autoconf. Regards, Thomas

Subject: [PATCH] Fix for pgcc -E output.
