net_db.c, read.c, socket.c: Update error messages to use ~A for %s, ~S for %S to work with new `simple-format' format and be standardized better. * print.h, print.c (scm_simple_format): Added `simple-format' primitive. It's the old scm_display_error, with ARGS now a rest parameter, and the destination first instead of last (and a couple new capabilities inspired by `format' -- #t as destination means current-output-port, #f means return the formatted text as a string. * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications. * backtrace.c (scm_display_error_message): Rewrote to use scm_simple_format() procedure. * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
