            Bug ID: 104861
           Summary: s-oscons.ads should use target_noncanonical
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org
  Target Milestone: ---

It seems that gprbuild uses Target_Name to construct paths to find files of the
installed gnat but when you configure GCC with a non-canonical target name
like --target=x86_64-suse-linux (omitting -gnu) then make install will use
@target_noncanonical@ for the directory.  That causes the gprbuild tools to
fail to build.

A solution might be to do the following and base Target_Name on
@target_noncanonical@ instead.
