figure that out; this usually happens when one variable is only
initialized and used when a particular condition holds true, and
we know that condition will never change within a given invocation
of the function. In this case, we simply initialize the variables
to placate the compiler, hopefully to a value which will cause a
crash if it is ever actually used.
* print.c (scm_iprin1): Initialize mw_pos.
* read.c (scm_lreadrecparen): Initialize tl2, ans2.
* throw.c (scm_ithrow): Initialize dynpair.
* unif.c (scm_uniform_vector_ref): Initialize cra.
* struct.c (init_struct): Initialize prot.
* mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.

variables aren't used uninitialized.
* error.h (scm_error, scm_syserror, scm_syserror_msg,
scm_sysmissing, scm_num_overflow, scm_out_of_range,
scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
scm_misc_error): Tell GCC that these functions never return.
* struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
out the field type, call abort if SCM_ASSERT returns, to placate
the optimizer.
* stacks.c (scm_make_stack, scm_last_stack_frame): abort if
scm_wta ever returns. We can't handle this case anyway, and this
gives the optimizer more information.
* unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
scm_wta ever returns.
In some cases, the code is fine, but GCC isn't smart enough to
figure that out; this usually happens when one variable is only
initialized and used when a particular condition holds true, and
we know that condition will never change within a given invocation
of the function. In this case, we simply initialize the variables
to placate the compiler, hopefully to a value which will cause a

(scm_must_malloc, scm_must_realloc): Added a hysteresis to the
rules for raising scm_mtrigger. Previously, unfortunate but not
unlikely circumstances could result in almost constant invokation
of the gc. Now, this situations should be less likely, but they
are not prevented completely.

scm_string_set_x scm_string_equal_p scm_string_append):
Bugfix according to scm patch from Aubrey Jaffer:
Corrected long-standing

Scheme.
* throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
(scm_internal_catch): New function, replaces...
(scm_catch_apply): Deleted.
* throw.c (scm_catch_apply): Deleted; replaced with a more general
mechanism which is a bit more code, but can be used nicely from C
and implement the Scheme semantics as well.
(scm_internal_catch): This is the replacement; it's named after
the analogous function in Emacs.
(scm_catch): Reimplemented in terms of the above.
(struct catch_body_data, catch_body, catch_handler): New
functions, used by scm_catch.
* root.c (cwdr): Reimplemented in terms of scm_internal_catch.
(struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
support for new cwdr.

Added "dynl.c".
(modinclude_HEADERS): Added "dynl.h".
(EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
"dynl-vms.c".

initialize dynamic linking support.
* init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
(as we Schemers say). It needs to be global, so that I can tweak
it for the proper operation of unexec.
(scm_boot_guile_1_live): New variable, see above.
