I need the struct member

__jmp_buf __jmpbuf;         /* Calling environment.  */

in the defintion of  jmp_buf[1];

e.g.:
#include <setjmp.h>
static jmp_buf  env;

/*extract the FP from env */
fp=(void *)env->__jmp_buf[JMPBUF_FP];

this doesn't work with djgpp's setjmp.h or do I understand something wrong ?
