 Thanks, I've closed it.  The consensus was that this is not a bug.

 Richard's verdict was that we should be going through make
 install_headers in glibc first instead of worrying about this.

 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?

    What version of libc are you trying to bootstrap on?
    I am trying to come up with a patch that addresses
    this problem when trying to bootstrap on glibc 2.0, which
    lacks sys/ucontext.h.

>Description:
MD_FALLBACK_FRAME_STATE_FOR wants to be able to unwind
the stack through signal frames, so it uses <signal.h> and <sys/ucontext.h>
to find the sigcontext's members.  If you do not have a libc for your target, libgcc can not be compiled, because those headers are not found.

It's easy to work around this by adding #ifndef inhibit_libc, but the compiled
copies are included in a glibc built with that compiler (currently), and
so stick around.  I should not have to rebuild glibc a second time just to get
this correct.  Would hardcoding the necessary offsets or structures be an
acceptable alternative to including the header files?  If so, I can make a patch.
