Apart from that, not only Cygwin DLLs but also the Windows system DLLs
are all loaded and relocated to the area beyond 0x1:80000000, so relocation
beyond the 32 bit address space is no generic problem in Windows.  Why
isn't that possible in FlexDLL?  I don't understand this.  To me this looks
like a bug in FlexDLL, not a requirement to let certain DLLs slip through
the cracks.
