--- Comment #3 from Nikhil Benesch <nikhil.benesch at gmail dot com> ---
For posterity, I could reproduce this issue even with the suggested
`./configure` arguments, i.e., excluding the `--enable-multilib` option.
The issue for me was that some of the configure checks in the gcc directory
were misfiring because they were unable to find gmp.h, though the top-level
config script had no trouble finding gmp.h. This caused configure to determine
that e.g. strsignal's declaration was missing, when in fact it was gmp.h that
could not be found.
I worked around the issue by using the ./contrib/download_prerequisites script
to build in-tree copies of gmp and friends. I suspect there is still a bug
here, though, when attempting to use the system's libgmp.
