Dear Mathias Klose(of ubuntu/debian):
I am in Ubuntu10.04(but upgrade kernel to 2.6.35-25 through cache)
and self build from(4.4.3 unbuntu's cache) to 4.5.2
but my system not work well in locale and gnu/gcc 's helper
told I probably need to switch from generic to gnu

Is that in 'mtune=generic'
to gnu ?
(guy told me as --enable-clocale=gnu)
because my /generic/c_locale.cc
restrict me too much comparing to /gnu/c_locale.cc
in my /gcc-4.5.2/libstdc++-v3/config/local/ directory
although I don't mind to upgrade/update to higher version of kernel or
gcc/g++, short way by modify configure's internal setting is better for
me.
/* I ever tried to copy/overwrite c_locale.cc in gnu/ directory to
* generic/ directory, then rebuild. But at stage of make, it stop/
* abort/failed by a lot of errors.
* I also check INSTALL directory, build/configure.html, it didn't

this time it compile well (no error)
