Could a gatekeeper please review a few minor fixes for building on
Fedora 17 with gcc 4.7?  With these changes I was able to get a clean
build.

Here is the proposed commit message and the diffs:


Fix compilation errors reported by gcc 4.7 on Fedora 17.

In the template function Unwind (wn_tree_util.h), qualify Set_wn member
function calls with "this->".

In Delete_All_Distr_Pragmas (lego.cxx), use a different name for the
inner loop index.

In ipa_nystrom_alias_analyzer.cxx, include <unistd.h> to get the prototype
for sbrk().
