It appears I have the latest version (gcc, g++, 4.5.3-6, 
runtime runtime-3.0b_svn5747-1, headers-3.0b_svn5747-1) offered by 
mirrors.kernel.org (checked prior to this email via setup against then current, 
and installed /var/log/setup.log), which is listed at
http://cygwin.com/mirrors.html 
as an up-to-date mirror.
 
1)Please advise what pkg version, mirror, or ? can provide appropriate build context.
2)Should configure check for and advise of possible problems with 'incorrect' version
of mingw64?
 
Thanks.
