if use -std=c++0x, will error:

d:\ycdeng\qpdev\bin\..\lib\gcc\mingw32\4.4.1\include\c++\cwchar|159|error:
'::swprintf' has not been declared|
d:\ycdeng\qpdev\bin\..\lib\gcc\mingw32\4.4.1\include\c++\cwchar|166|error:
'::vswprintf' has not been declared|
||=== Build finished: 2 errors, 0 warnings ===|

if want fix, need #undef __STRICT_ANSI__, see: stdio.h
or option is: -U__STRICT_ANSI__

but when change to: -std=gnu++0x, it's OK!
