Comment 4 for bug 1538247

Ooops, I've just noticed that you have already applied the patches.

Next patches will be in the form of a single file. They will be rather cosmetic because I try to fix warnings reported by -Wall option. Some of them are annoying, eg. like warning about signed/unsigned comparison in templates:

It takes some effort to understand this.
