* error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>. * strings.c (scm_string_ref): make the 2nd argument compulsory. previously it defaulted to zero for no good reason that I can see. use a local variable for SCM_INUM (k). replace SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY. (scm_makfromstr): cosmetic changes. (scm_string): Accept only chars in the list, not strings, for conformance to R5RS (particularly for list->string, which is supposed to be the inverse of string->list.) remove SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since scm_makstr handles the cell allocation. when reporting wrong-type arg, don't report the position as 1. * posix.c (scm_init_posix): intern PIPE_BUF if it's defined. * boot-9.scm (find-and-link-dynamic-module): pass strings, not symbols, to string-append.
