Yes, because the resource compiler is not specified.

Symptoms of a missing resource compiler.

That would be an option, yes.

I configure gcc like this

using gcc : 
          : # compile-command                   
            i386-mingw32-g++
          : #options
            <rc>i386-mingw32-windres
            <archiver>i386-mingw32-ar
          ;

you just have to add <rc> and maybe <archiver> for static linking.

Yours,

Jürgen
