Sorry for blasting the list.  Adding "-mri -mregnames" gets past this problem.  "-mri" eliminates the need to supply the "\" in the macro definitions, "-mregnames" adds symbolic names such as r1.  The macro expansion in GAS must be done in a way that the normal definition of the register names used everywhere else in the assembler file is bypassed, so you need "-mregnames".
