* win32-nat.c: Fix up gcc warnings throughout.

Browse Source 
(handle_load_dll): Change DLL name to lower case.
(handle_exception): Add a second argument indicating whether a breakpoint
should be ignored.  Return a 0 if the breakpoint was ignored.
(get_child_debug_event): Pass argument to handle_exception to control whether a
breakpoint should be ignored.
(child_create_inferior): Use modern cygwin API.  Explicitly clear last_sig.
Pass FIRST_EXCEPTION to get_child_debug_event for detection of first
breakpoint.

* configure.in: Eliminate unneeded WINDRES/DLLTOOL tests left over after last change.
* configure: Regenerate.
