Please edit your config.h file, and remove the reference to "-malign-double".
[To me this looks like an error in the configure script, cc-ing to
amber-developers. The underlying problem is that MacOS 10.5 (unlike 10.6, God
only knows what will happen with Lion) makes everything look like a 32-bit OS.
I've never, however, seen any version of gcc that would not accept the
-malign-double flag, but the number of possible combinations in Apple-land
is truly mind-boggling....I have an old laptop that still has 10.5 on it, so
I'll try to investigate further.]
