+// Purpose:       POSIX sigsetjmp header
+// Description:   This header contains all the definitions needed to support
+//                the POSIX sigsetjmp/siglongjmp API under eCos.
+//              
+// Usage:         This file must be included indirectly via
+//                the C library setjmp.h header.
