Cygwin doesn't implement its own binary executable loader like ld.so on Linux. Apart from allowing to start shell scripts per execve(2), we depend on the Windows PE/COFF Loader. Therefore, we can't support non-PE/COFF binaries. As a sidenote, way back when porting Cygwin to 64 bit, it has been discussed to convert Cygwin binaries to ELF and use some kind of dynamic loader executable like ld.so. However, our budget was pretty low, and the work involved in creating such a new loader on Windows was deemed too expensive/complicated. Having said that, anybody taking a stab at something like that would have our keenest support.
