[yocto] usage of mingw as external toolchain

[Francisco Torres]

Hello,

I need to use mingw32 as external toolchain with yocto.

I have successfully built a helloworld recipe (as explained in http://www.yoctoproject.org/docs/1.0/poky-ref-manual/poky-ref-manual.html#usingpoky-extend-addpkg, 3.1.1. Single .c File Package (Hello World!)) and it is successfully generating a .exe that I can run on Windows.

The problem is that when I try to compile an autotooled package (as explained in same page in 3.1.2. Autotooled Package), there is a compilation problem.
Please I need help to solve this problem.

I am adding in conf/local.conf

EXTERNAL_TOOLCHAIN = "/path/to/your/mingw32-install"


The log is:
