Hi. When compiling the libhubbub tests from git master using GCC 4.7.2 I get two warnings, which become errors via -Werror and stop the tests running: error: variable `origlen` set but not used [-Werror=unused-but-set-variable] error: comparison between `parserutils_error` and `enum hubbub_error` [-Werror=enum-compare] The following (git format-) patch makes the errors go away and the test suite pass: https://gist.github.com/craigbarnes/5514898/raw/c2f94d97d26b52b01e5cf45c2... Aside: I discovered the errors while working on a hubbub package/binding for the Lua language, which can be found at: https://github.com/craigbarnes/lua-hubbub ...if anyone is interested. It's MIT licensed and should be complete in a few days.
