Subject: [PATCH] Sten Spans found a solution for the problem noted by Jose
 Arthur Benetasso Villanova that he could not override our CXXFLAGS. 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!
