//
// This module is included to suppress NT's annoying behaviour of
// popping up an 'unhandled exception' dialog box whenever a segment
// violation occurs -- or other special errors that occur only on nt.
//
// When used, this object module MUST BE FIRST in your link order!
//

// This stuff superseeds the default OS exception handler -- when exceptions
// occur, the program dies WITHOUT putting up a dialog box.  This must be
// the first object module linked into your executable to ensure that static
// initializations that cause errors do not pop up annoying dialog boxes that
// hang build scripts -- instead they merely crash producing error messages.
//
// Note that if this module is not linked first, it will still work -- but
// will not protect object modules linked earlier!  It really should be first.
