Don't worry about it.  There are enough people compiling with newer gcc

heard that too often ;-)
I've send out a new version of the patch (in fact a new series)
disabling the warning with a pragma only in the affected file.

But isn't the problem that the use of pragmas to silence broken warnings
is specific to newer gcc, while you are trying to silence the warning on
older gcc?  I guess I'll have to look at what you did; and I still need
to work up my patch for the warning avoidance at configure time anyway.

obviously I can't vouch for it ... but according to the GCC manuals,
-Wlogical-op was introduced in gcc 4.3 while #pragma GCC diagnostic
showed up in gcc 4.2, so we should be safe.
But then again, I said that too often as well ...
