* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES): (DOT_X_FILES, DOT_DOC_FILES, noinst_HEADERS): Add syntax.c and syntax.h. * libguile/evalext.c (scm_self_evaluating_p): * libguile/goops.c (class_syntax, scm_class_of, scm_goops_early_init): * libguile/init.c (scm_init_guile): * libguile/print.c (iprin1): * libguile/tags.h (scm_tc7_syntax): * module/oop/goops.scm (<syntax>): * module/system/base/types.scm (%tc7-syntax, cell->object): * module/system/vm/disassembler.scm (code-annotation): Wire up the new data type. * libguile/syntax.c: * libguile/syntax.h: New files. * module/ice-9/boot-9.scm: Move new definitions to (system syntax internal). * module/system/syntax.scm (print-syntax): New helper. * module/system/vm/assembler.scm (statically-allocatable?) (intern-constant, link-data): Arrange to be able to write syntax objects into images. * module/language/cps/types.scm (&syntax): New type. Remove &hash-table; it was never detected, an internal binding, and we need the bit to avoid going into bignum territory.
