* guile-doc-snarf.awk: Removed.

* guile-doc-snarf.awk.in: Added.

* ports.c (s_scm_pt_member): Fixed validation.

* guile-doc-snarf.in (filename): Use basename in order to strip
away path.

semicolon.

strings to new form.

* backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.

* tags.h (SCM_UNBOUND): New iflag which is needed for some time to

replaced with SCM_UNDEFINED when the corresponding code in GOOPS
is rewritten.)

SCM_UNBOUND.

* eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
SCM_IM_SLOT_REF.
