5579919f7d * Makefile.in (scm-exp.o, scm-lang.o, scm-valprint.o): Add targets and
dependencies.
	* scm-lang.c (gdb_string.h): Include.
	* objfiles.c (add_to_objfile_sections): Cast second arg of obstack_grow
	call to correct type (char *).
	* cp-valprint.c (cp_print_static_field): Ditto.
	* somsolib.c (som_solib_create_inferior_hook): Add a declaration
	for external find_unwind_entry function (from hppa-tdep.c).
	* remote-pa.c (remote_write_bytes, remote_read_bytes): Change
	type of second arg to "char *" to be type compatible with
	dcache.
	(remote_wait): Cast second arg to strtol to correct type.
	* hppa-tdep.c (compare_unwind_entries): Change argument types to
	"const void *" to be type compatible with qsort, and then
	assign to local args prior to use.

a4f39c0651 * somsolib.c (som_solib_create_inferior_hook): Before returning
call clear_symtab_users.
Fixes minor hpux problem with 7763 patches.

ff7f8f2d1e * symtab.h (looup_minimal_symbol_solib_trampoline): Declare.
Minor build nit.

        * breakpoint.h (remove_solib_event_breakpoints): Declare.
        * breakpoint.c (remove_solib_event_breakpoints): New function.
        * somsolib.c (solib_create_inferior_hook): Remove all solib event
        breakpoints before inserting any new ones.  Use a solib event
        breakpoint for the breakpoint at "_start".
        Remove extraneous "\n" from calls to warning.
Don't leave bogus breakpoints in the breakpoint chain.  Simplify
solib_create_inferior_hook and allow for debugging of startup code
(more 7763 related changes).

        * breakpoint.c (breakpoint_1): Add missing "sigtramp" to bptypes
        name array.
Another minor nit.

        * breakpoint.c (bpstat_what): Add shlib_event to the class types.
        Update state table.  Reformat so that it's still readable.
        When we hit the shlib_event breakpoint, set the calss of shlib_event.
        (breakpoint_1): Add "shlib events" as a breakpoint type.
        Print the shlib_event breakpoint like other breakpoints.

        (normal_stop): Inform the user when the inferior stoped due
        to a shared library event.
        (_initialize_infrun): Add new set/show variable "stop_on-solib-events"

        a shared library event occurs.
        * minsyms.c (lookup_minimal_symbol_solib_trampoline): New function.
        * somsolib.c (TODO list): Update.

code to automatically track shl_load/shl_unload calls on hpux.

95037710ca * somsolib.c (som_solib_add): Just give a warning if a file
mentioned in the dld_list can't be found.
Warning seems more reasonable than croaking.

        * config/pa/tm-hppah.h (FRAME_SAVED_PC_IN_SIGTRAMP): Dig out
        the PC from the PC queues rather than %r31.
Fixes net bug.  Might also fix one of the hpux10 corefile.exp failures,

156285aac0 * somsolib.c (som_solib_add): Validate regexp argument.
