somehow the build scripts pick up the wrong compiler and I have no clue
why.

-------------------
configure:2642: checking for i586-mingw32msvc-gcc
configure:2669: result: gcc
configure:2938: checking for C compiler version
configure:2947: gcc --version >&5
gcc (Debian 4.6.1-4) 4.6.1
-------------------

I will probably need some more time to get this working...
