RPATH is an ELF feature. Full paths to DLLs are not supported by the PE/COFF executable format. Also, Cygwin DLLs are still loaded by the Windows loader, so POSIX paths won't work, and full Windows paths won't make much sense, given that Cygwin is not always installed into C:\cygwin. The solution for this would be an ELF loader in Cygwin and a Cygwin linker which produces ELF DLLs by default. But that's quite a big project on its own and nobody seemed to have fun, time, or money, to implement this.
