Failed build on mingw

Hi all, first of all, sorry for my english. I'm trying to do it better.
I'm trying to compile and build libgd on mingw using msys (linux like
console subsystem) I downloaded gd-2.0.35 from your homepage and running
as you say. But make have failed with that output:
        make  all-recursive
        make[1]: Entering directory `/home/enrique/build/gd-2.0.35'
        Making all in config
        make[2]: Entering directory
        `/home/enrique/build/gd-2.0.35/config'
        make[2]: Nothing to be done for `all'.
        make[2]: Leaving directory
        `/home/enrique/build/gd-2.0.35/config'
        Making all in test
