+setjmp.h \- stack environment declarations
+.SH SYNOPSIS
+.LP
+\fB#include <setjmp.h>\fP
+.SH DESCRIPTION
+.LP
+Some of the functionality described on this reference page extends
+the ISO\ C standard. Applications shall define
+the appropriate feature test macro (see the System Interfaces volume
+of IEEE\ Std\ 1003.1-2001, Section 2.2, The Compilation Environment)
+to enable the visibility of these symbols in this
+header.
+.LP
+The \fI<setjmp.h>\fP header shall define the array types \fBjmp_buf\fP
+and \fBsigjmp_buf\fP.
+.LP
+The following shall be declared as functions and may also be defined
+as macros. Function prototypes shall be provided.
