* README: Document dependency on GNU libunistring. * benchmark-suite/Makefile.am (SCM_BENCHMARKS): Add `benchmark/bytevectors.bm'. * configure.in: Make sure we have libunistring; update $LIBS. * libguile.h: Include "bytevectors.h" and "r6rs-ports.h". * libguile/Makefile.am (libguile_la_SOURCES): Add `bytevectors.c' and `r6rs-ports.c' (DOT_X_FILES): Add `bytevectors.x' and `r6rs-ports.x'. (DOT_DOC_FILES): Add `bytevectors.doc' and `r6rs-ports.doc'. (noinst_HEADERS): Add `ieee-754.h'. (modinclude_HEADERS): Add `bytevectors.h' and `r6rs-ports.h' * libguile/validate.h (SCM_VALIDATE_BYTEVECTOR): New macro. * module/Makefile.am (SOURCES): Add $(RNRS_SOURCES). (RNRS_SOURCES): New variable. * test-suite/Makefile.am (SCM_TESTS): Add `bytevectors.test' and `r6rs-ports.test'.
