You didn't send cygcheck output...

If you are using a cmd.com terminal, you do it like you would copy and
paste anything else from Windows - right click on the title bar, hit
edit->mark, highlight the text, then right click on the title bar and
select copy.  If you are using rxvt or xterm, you do it like you would
copy and paste anything else from Unix - highlight the text, and it is
already on the clipboard.

And if all else fails, redirect your output to a file, and just attach the
file.

As for the size of cygcheck -svr, we know about that - we wouldn't ask for
it if it weren't important, in spite of the size.

The contents of config.log are still important for seeing why configure
didn't like your gcc setup.
