There are several warnings in the file /libcroco/cr-om-parser.c, which the attached patch fixes.

I should discuss with Dodji (the upstream maintainer) what his preferred approach would be.
If we are never modfying these files, then the warnings will not appear anyway. You might want to close this as WONTFIX
