In commit 20f818af1201277 I renamed a lot of variables called 'ret',
by using clang-rename to do the heavy lifting. But clang-rename only
saw instances of the variable name that the _compiler_ saw. The ones
that never got through the preprocessor weren't renamed, and I didn't
eyeball the patch hard enough to find instances in the #else branch of
ifdefs that should also have been renamed.
Thanks to Lars Wendler for the report and the fixes.
