Weird warning message (".drectve `-defaultlib:crt' unrecognized")

[timeout]

Hello,

I used codeblocks under windows and I am developing a project in C using mingw-gcc. This project also used an external C library.

When I compile my project I have the following warning :

Code

Warning: .drectve `-defaultlib:crt' unrecognized

Do you know where "-defaultlib" switch come from and how can I set it (or unset it) ?

Regards,
