Hiho!

 I don't know exactly how but my defined CFLAGS are overridden by
 the made Makefiles in gcc and subdirs. Behause of the inheritance of
 variables that are defined in Makefiles it should be enough to define
 them in the topdir of the tree but they are defined in every single subdir.

 Further we have a nice autoconfig screict which figures out what
 options to use to compile the whole thing. But they will be only used
 if we substitute all CFLAGS and CXXFLAGS with @CFLAGS@ and
 @CXXFLAGS@. This will also allow to remove the whole debugging
 thing simply by a added option to the autoconf script which will follow
 in the next days. 
 But first here's the patch to remove hardcoded CFLAGS:
