to 'misc-error instead of 'error (no need to distinguish these.)
Don't set up 'error as a key.
Set up regex-error as a key, if regex is available.
(signal-handler): use scm-error, not throw.
(%try-load, try-load-with-path, %load, load-with-path,
basic-try-load-with-path, basic-load-with-path,
try-load-module-with-path,load-module-with-path): deleted, since
they seem redundant.
(try-load): define using %try-load, not try-load-with-path.
(load): rewritten. load tries to open the file directly and
with a .scm extension before searching the library directories
(should "." be added to %load-path? then load could still open
directly files starting with "/").
(try-module-autoload): use load, not load-with-path.
(%load-indent): deleted, -2 was causing errors.
(%read-sharp): use port-line, not line-number.
%try-load itself was the primitive.
(load-with-path): use scm-error instead of %load-announce-lossage.
Errors are thrown to 'misc-error instead of 'could-not-load.
(%load-announce-lossage): deleted.
SCM-style errors. handle the case that an unexpected number
of args are supplied.
(%%system-errors): removed.
(error): redefine using a throw with key and 4 args.
('error): associate 'error, 'error-signal keys with
%%handle-system-error.
(%%default-error-handler): removed.
(signal-handler): throw with 4 args and use the error-signal key.
Create an error message instead of using numerical codes.
(%%bad-throw): call error instead of throw if key not found.
* boot-9.scm: initialize new error keys (see libguile/ChangeLog).
(%%handle-system-error key): check subr is not #f before printing.
Recognize %s (embed an argument using "display") and
%S (embed an argument using "write").
* PLUGIN/guile.config (xtra_dependencies): add only libgh.a.
(xtra_cflags): just add -L../lgh
* PLUGIN/guile.libs: try -lgh -lguile
* Makefile.am (INCLUDES): add -I../ so that libguile/scmconfig.h can
be found when srcdir != build dir.
* PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
* error.c, error.h: setup scm_num_overflow key.
* __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
Remove definition of SCM_OVSCM_FLOW.
* fports.c (scm_open_file): use SCM_SYSERROR_M.
* __scm.h: SCM_SYSERROR_M: new macro for system errors with an
explicit message and args.
* error.c, error.h, __scm.h: change system_error_sym to
scm_system_error.
* error.c (system_error_sym): remove leading %% from the Scheme name
"%%system-error".
* __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
* boot-9.scm: remove leading %% from references to '%%system-error.
(%%handle-system-error): don't pass all the thrown arguments when
aborting, just the key and subr.
Remove the code to "Install default handlers for built-in errors."
Remove the definition of the syserror procedure.
Associate 'numerical-overflow with default handler.
