  I've also run into this problem. I acknowledge mine's not a quite common 
configuration: cross gcc-4.2 toolchain from emdebian and a tailored ecos 
version from Vitesse which should be quite close to 2.0 release.

  Thing is that I've applied the patch successfully and I was able to go on 
with the compilation. I still have other issues, but I understand that ecos 
building is just supported under toolchain provided by ecos web.

  HTH,
