 To append info to a GNATS entry, make sure you CC:
 gcc-gnats@gcc.gnu.org, and make sure that the Subject:
 field of your e-mail contains the GNATS ID for the Problem Report,
 ie.
 
 "Subject:  Re: Re: bootstrap/3641: can not bootstrap on....."
 
 If you can figure out a good place to put this in documentation,
 I'll write a patch for it.

 There is a patch very similar to what you are talking about,
 but meant to address the problem of bootstrapping on
 older versions of glibc.
 
 I submitted this patch, to detect the existence of ucontext.h
 in the configure script:
 
 http://gcc.gnu.org/ml/gcc-patches/2001-10/msg01543.html
 
 The next part of the patch, which I have not tested yet is
 here:
 http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view&pr=4068&database=gcc
 
 Does that patch look like it would work for your problem?
