+
+ * config/i386/tm-cygwin.h: include tm-i386.h instead of tm-i386v.h.
+ This fixes errors in "long long" handling for 'finish' and 'return'
+ commands.
+
+2001-10-12 Christopher Faylor <cgf@redhat.com>
+
+ * win32-nat.c (safe_symbol_file_add_stub): Avoid adding a shared
+ library if it has already been loaded.
+ (safe_symbol_file_add_cleanup): Don't mess with stderr or we won't see
+ any error messages.
+ (safe_symbol_file_add): Ditto.
+ (solib_symbols_add): Make static. Accept 'from_tty' parameter. Pass
+ it to safe_symbol_file_add.
+ (core_dll_symbols_add): Accomodate extra solib_symbols_add parameter.
+ (child_solib_add): Ditto.
+
+ * win32-nat.c (handle_exception): Don't print "first chance"
+ exceptions.
+ (get_child_debug_event): Continue from exceptions if !handle_exception.
+
2001-10-11 Tom Tromey <tromey@redhat.com>
* symtab.c (lookup_symtab): Removed.
