Well, it turns out that Apple's gcc default >configuration causes this flag to produce binaries *exclusively" for >the G5 architecture... how do you like that?? Thank you so much for finding that. I don't think I'd've found it on my own. I've now replaced "-fast" by "-O2" in the makefile. Simplest solution and reasonably portable. If I understood the autoconf shit (:-/) better I would repair that: from the log file you can clearly see that it compiles some test file with "-fast", and if that succeeds it accepts the option. It should actually run it. Btw, elsewhere someone suggested doing "otool -h" on the executable. That gave me (with /usr/include/mach/machine.h) the information that the executable was for PowerPC 970. Anyway. We're off and running.
