I'm trying the patches.  Make check is still going and this should
take the couple more hours.  But it's already obvious that nothing has
changed into the something better...  I've a lot of failures for
libstdc++.  The most of them look like:


FAIL: 22_locale/num_get/get/wchar_t/1.cc execution test
FAIL: 22_locale/num_get/get/wchar_t/2.cc execution test
FAIL: 22_locale/num_get/get/wchar_t/3.cc execution test
FAIL: 22_locale/num_get/get/wchar_t/5.cc execution test
FAIL: 22_locale/num_get/get/wchar_t/6.cc execution test
FAIL: 22_locale/num_get/get/wchar_t/9.cc execution test


BTW, as I can see, the test sources are compiling w/o
-fomit-frame-pointer.  And the only optimization is -O2.  And it's
strange by itself.
