misreported bug and gnats trouble

1) The email address for the gnats admin seems to be
address@hidden

2) Bug 4141, reported by me, is evidently not a glibc bug.  I wrote that
the following code produced an fp exception on an Alpha '264:

#include <stdio.h>
#include <math.h>
int main(void)
{
  double en;
  en = exp( -709);  /* bad between 708 and 745 */
  if (en) fprintf( stderr, "it worked\n");
  return 0;
}

/* compile with probably anything: gcc -o foo foo.c is fine. */

I tried to work around this problem with a pathetic linear interpolation
with values taken from an x86-based computer.  However, my linear
interpoloation stage failed, suggesting that this problem is not
necessarily related to glibc.  I am now guessing that gcc 2.96 or kernel
(2.4.9-31 from RH, or 2.4.19-pre8) is to blame.  Any help would still be
welcome, of course -- this problem has been a show-stopper for us.
