 *		SignalProc32 (USER.391)
 *		UserSignalProc (USER32.@)
 *
 * The exact meaning of the USER signals is undocumented, but this
 * should cover the basic idea:
 *
 * USIG_DLL_UNLOAD_WIN16
 *     This is sent when a 16-bit module is unloaded.
 *
 * USIG_DLL_UNLOAD_WIN32
 *     This is sent when a 32-bit module is unloaded.
 *
 * USIG_DLL_UNLOAD_ORPHANS
 *     This is sent after the last Win3.1 module is unloaded,
 *     to allow removal of orphaned menus.
 *
 * USIG_FAULT_DIALOG_PUSH
 * USIG_FAULT_DIALOG_POP
 *     These are called to allow USER to prepare for displaying a
 *     fault dialog, even though the fault might have happened while
 *     inside a USER critical section.
 *
 * USIG_THREAD_INIT
 *     This is called from the context of a new thread, as soon as it
 *     has started to run.
 *
 * USIG_THREAD_EXIT
 *     This is called, still in its context, just before a thread is
 *     about to terminate.
 *
 * USIG_PROCESS_CREATE
 *     This is called, in the parent process context, after a new process
 *     has been created.
 *
 * USIG_PROCESS_INIT
 *     This is called in the new process context, just after the main thread
 *     has started execution (after the main thread's USIG_THREAD_INIT has
 *     been sent).
 *
 * USIG_PROCESS_LOADED
 *     This is called after the executable file has been loaded into the
 *     new process context.
 *
 * USIG_PROCESS_RUNNING
 *     This is called immediately before the main entry point is called.
 *
 * USIG_PROCESS_EXIT
 *     This is called in the context of a process that is about to
 *     terminate (but before the last thread's USIG_THREAD_EXIT has
 *     been sent).
 *
 * USIG_PROCESS_DESTROY
 *     This is called after a process has terminated.
 *
 *
 * The meaning of the dwFlags bits is as follows:
 *
 * USIG_FLAGS_WIN32
 *     Current process is 32-bit.
 *
 * USIG_FLAGS_GUI
 *     Current process is a (Win32) GUI process.
 *
 * USIG_FLAGS_FEEDBACK
 *     Current process needs 'feedback' (determined from the STARTUPINFO
 *     flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
 *
 * USIG_FLAGS_FAULT
 *     The signal is being sent due to a fault.
