            Bug ID: 113181
           Summary: When compiling sanitizer_printf.cc, getting error:
                    multiple definition of ‘enum fsconfig_command’
           Product: gcc
           Version: 8.5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: eyalroz1 at gmx dot com
  Target Milestone: ---

I'm building GCC 8.5.0 on a Devuan GNU/Linux Excalibur machine (~= Debian
Trixie).

I've encountered, and worked around, the libstdc++ mixup bug (bug 87858), so
now I have my distribution's static 32-bit libstdc++ installed. Anyway, with a
build configured like so:

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

I get, at some point, the following warning + (unrelated?) error:
