// BEGIN_WINDOWS_VEH_HANDLER  and END_WINDOWS_VEH_HANDLER, which
// will catch such exceptions in the entire process and die by
// printing a message and calling stg_exit(1).
//
// For other operating systems an empty macro is defined so
// that no #ifdefs are needed around the usage of these macros.
