a complie error ?

[William]

I am using mingw and msys, there is a complier error:

........

but when I use mingw attached by CodeBlocks, it is OK.

gcc and STL of mingw is 3.4.2, that of ClodeBlocks is 3.4.3
Is there any difference between them ?

thanks in advance !

I copied STL 3.4.4 to mingw, and it's OK now,
it seems a STL incompliant.
