GNU autoconf allows to set up "default results" for cross compiling when trying 
to test things that need to run on the target.

Some of the basic GNU text utils either return most pessimistic values in case 
of a cross compilation or someone did handcraft the related results for MinGW 
and publishes such a modified source that probably will no longer compile 
correctly on other systems.

BTW: I introduced the cross compilation extensions to schily autoconmf in order 
to permit to compile my software for android.
