Note that your list of files that differ contain .a, .o and .c files. The .c and .o differences are explanable, but I don't see how a linker flag affects .a files. There's no linking involved anywhere.

I think something fishy is going on on pluto2. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
