* win32-nat.c (psapi_get_dll_name): Fix a compiler warning.
(struct so_stuff): Add end_addr field.
(register_loaded_dll): Calculate and store end address of loaded dll.
(solib_address): New function.
(child_solib_loaded_library_pathname): Pass carefully constructed section info
to safe_symbol_file_add rather than ignoring it.
(get_child_debug_event): Call re_enable_breakpoints_in_shlibs when a DLL is
loaded.
(do_initial_child_stuff): Call disable_breakpoints_in_shlibs.
(child_create_inferior): Fix a compiler warning.
* config/i386/tm-cygwin.h (PC_SOLIB): Define new macro.
(solib_address): Declare new function.
