-fpermissive for CFLAGS and CXXFLAGS is it needed now -- why?

Tim, Serghei, All: I ran into an earlier build error with amarok that indicated a '-fpermissive' problem, so I added the flags Baho had set in other files that let amarok build further until I hit the undefined reference to `Amarok::aboutData' error. Why the new need for: CFLAGS=${CFLAGS}" -fpermissive" CXXFLAGS=${CXXFLAGS}" -fpermissive" in the build? -- David C. Rankin, J.D.,P.E.
