Oh, that enables warnings (i.e., it looks for lint), but it is not compiling with -DGCC_LINT. In general we don't need to support that combination, any more than we need to support lint checking with random compilers.
This probably explains why you saw the problem with diffutils but I didn't. Possibly you built diffutils with -Wall only. I configure diffutils with --enable-gcc-warnings, which does more checking than -Wall does, and also defines GCC_LINT. (Perhaps someday gettext could do something similar, but that'd be a bigger project.)
It's not worth changing diffseq.h back since the change is innocuous. But I hope we don't need to do much more of this sort of makework.
