+On AIX, Darwin, and 64-bit PowerPC Linux, the option
+@option{-malign-natural} overrides the ABI-defined alignment of larger
+types, such as floating-point doubles, on their natural size-based boundary.
+The option @option{-malign-power} instructs GCC to follow the ABI-specified
+alignment rules. GCC defaults to the standard alignment defined in the ABI.
