I cannot reproduce such an error with the 3.7.16.2 tarball, even with 
autoconf-2.69 and automake-1.13.1.

For now, a workaround is to define WANT_AUTOMAKE=1.10 (or newer), as 
that is the first version whose config.guess detects x86_64-cygwin. 
Another workaround is to manually replace the config.{guess,sub} in 
libtool and all versions of automake with the copy included with 
cygport.  BTW, the same goes for i686, as this would affect 
cross-compiling to x86_64.

In the long term, we're probably going to want to make this work OOTB. 
There are a few ways to go about this; I'll try to work on a proposal soon.
