            Bug ID: 113188
           Summary: graphite-isl-ast-to-gimple.c: ‘isl_val_free’ was not
                    declared in this scope
           Product: gcc
           Version: 6.5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: eyalroz1 at gmx dot com
  Target Milestone: ---

I'm struggling trying to build GCC 6.5.0 on a newer system: Devuan GNU/Linux
Excalibur (~= Debian Trixie). I'm using the following configuration:

./configure --disable-libsanitizer --disable-bootstrap --enable-languages=c,c++

and at some point, I get a couple of compilation errors about undeclared
identifiers; the error is quoted below.

Is there some way I could circumvent these? e.g. by disabling another component
or replacing a version of some tool/library?
