Re: [PATCH] fix some clang warnings

It seems a little weird to me that clang defines __GNUC__, but I
assume there are good reasons for it.

The thing is that "gcc" is as much a language dialect these days as it
is a compiler implementation, and many other compilers, including
clang, explicitly try to implement that dialect (clang goes even
further by trying to be compatible in other ways, e.g. command-line
syntax, but that's not relevant here).

__GNUC__ is a way many programs try to detect the presence of a
compiler that implements that dialect, they have little choice but to
define it...
