This is just a quick suggestion. In the wiki page ABS - the Arch Build System, it mentions that ABS can be used a rebuild packages with custom compiler flags. However, it never indicates how this can be done. In fact the only reference on how to do this in the wiki that I can find is in the Post Installation Tips. I suggest that either these instructions for custom compiler flags be included in the ABS wiki page or a link be made in that page which directs one to the instructions in the Post Installation Tips page.
Sweet, now I can play with myself.
It's a wiki, so go ahead...
