The patch fails to bootstrap in libquadmath btw:

/space/rguenther/src/svn/trunk/libquadmath/math/cimagq.c:24:1: error:
redefinition of 'cimagq'
In file included from
/space/rguenther/src/svn/trunk/libquadmath/quadmath-imp.h:26:0,
                 from
/space/rguenther/src/svn/trunk/libquadmath/math/cimagq.c:21:
/space/rguenther/src/svn/trunk/libquadmath/quadmath.h:175:1: note: previous
definition of 'cimagq' was here
make[3]: *** [math/cimagq.lo] Error 1

which seems to make heavy use of gnu-inline always-inline.
