Cygwin special gcc will bootstrap all more recent gcc versions. Of course, there are Windows versions and Windows versions. Don't expect Windows versions from over 5 years ago, or an installation which doesn't do a clean file system or registry check, to work. Of course, watch out for buggy antivirus programs. If you are building libstdc++, you would need to remove the WERROR macros there, unless your headers meet the criteria set. The gcc source must be installed in a place such that there are no spaces in the path. On some installations, it is necessary to set HOME to the top level gcc source directory. Other than that, build on a multi-threaded platform if you want to finish within 8 hours. If you find that you had forgotten necessary software components in your cygwin installation, after installing them, start your gcc configure and build over from scratch. In my experience, cygwin automake is broken with respect to gcc builds, so don't install that.
