these badly pollute the namespace with macros whenever _GNU_SOURCE is defined, which is always the case with g++, and especially tends to interfere with C++ constructs. as our implementation of these was macro-only, their removal cannot affect any existing binaries. at the source level, portable software should be prepared for them not to exist. for now, they are left in place with explicit _LARGEFILE64_SOURCE. this provides an easy temporary path for integrators/distributions to get packages building again right away if they break while working on a proper, upstreamable fix. the intent is that this be a very short-term measure and that the macros be removed entirely in the next release cycle.
