Did you try to use the cygwin tarball as a source for Sage's R version ? BTW : could it be acceptable to have multiple tarballs as a source for R on different platforms ? Or different set of patches ? Another alternative : can the spkg-install script use only certain patches (as a function of the platform he's running on) ? In that case, a diff between the original tarball and the Cygwin-patced tarball could be applied if and only if one is installing on cygwin. What do you think ? I do not understand the Sage build system well enough to understand if this is possible, much less how...
