Sten Spans found a solution for the problem noted by Jose Arthur Benetasso Villanova...

New behaviour is that by default you still get our CXXFLAGS of -O2 -Wall, but if you specify your own CXXFLAGS during ./configure, yours win.
This means that everybody who only *added* using CXXFLAGS=-fsomething will now lose our default -O2!
