Hello,

In the combined tree there are directories like ./winsup/mingw/mingwex 
are three levels removed from the toplevel yet do have configure.in.  
Autoconf's AC_CONFIG_AUX_DIRS currently only look's two directories 
underneath to check for install.sh to discover the toplevel.  This tiny 
patch allows it to look three levels beneath.

I am also sending the obvious followup patch to m4/auxdir.m4 to the 
automake list so the aclocal.m4 comments about AC_CONFIG_AUX_DIRSget 
updated with this new functionality.
