* libguile/snarf.h (SCM_SYNTAX): Remove snarf macro, users can't define primitive syntax any more. * libguile/memoize.c (SCM_SYNTAX): Define locally, and just call scm_i_makbimacro as there's no difference between that and scm_makmmacro. Alter invocations to suit. * libguile/macros.h: * libguile/macros.c (scm_i_makmmacro): Remove; users can't define primitive syntax any more. Use define-syntax instead. (scm_make_synt): Remove, this was only used by the SCM_SYNTAX snarf macro. (scm_i_makbimacro): Change prototype of this internal function to make the gsubr on behalf of the caller. (macro_print, scm_macro_type): Remove cases for mmacros.
