            Bug ID: 18615
           Summary: scripts/sysd-rules.awk (via make process) causes a ton
                    of gawk warnings
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
          Assignee: unassigned at sourceware dot org
          Reporter: jamespharvey20 at gmail dot com
                CC: carlos at redhat dot com
  Target Milestone: ---

On arch, glibc-git and gawk 4.1.3, right after running configure, make causes a
ton of (duplicate) gawk warnings, through scripts/sysd-rules.awk.

Not sure (yet) if this is a harmless warning.

Even if it is, and the third argument to gensub is supposed to be 1, it would
be nice to pretty-up the build output by actually giving it 1.

Also happens at nptl/tst-cancel-wrappers.sh:77

Instead of 1 (or any other number) "g" could be intended, for a global
substitution.
