[PATCH 4/5] windows-nat: Report an error if ContinueDebugEvent() fails

[Jon Turney <jon.turney@dronecode.org.uk>]

Using error() seems appropriate here, if ContinueDebugEvent() fails, the
inferior is in an unknown state and we will probably not be debugging anymore...

gdb/ChangeLog:

2015-04-16  Jon Turney  <jon.turney@dronecode.org.uk>

	* windows-nat.c (windows_continue): Report an error if
	ContinueDebugEvent() fails.
