no it does, it was late yesterday:

diff --git a/solenv/gbuild/platform/WNT_INTEL_GCC.mk 
b/solenv/gbuild/platform/WNT_INTEL_GCC.mk
index b9edab0..70a4608 100644
--- a/solenv/gbuild/platform/WNT_INTEL_GCC.mk
+++ b/solenv/gbuild/platform/WNT_INTEL_GCC.mk
@@ -87,6 +87,7 @@ endif
 ifeq ($(HAVE_CXX0X),TRUE)
 # We can turn on additional useful checks with c++0x
 # FIXME still does not compile fully gb_CXXFLAGS += -std=gnu++0x
+gb_CXXFLAGS += -std=gnu++0x
 endif

did the trick. It was activated during the configure, but deactivated 
during compilation.
Not sure if i should commit that?
