  This much is expected.  It is not possible to use a Cygwin-native DLL without
the rest of the Cygwin runtime support present and correctly initialised, in
particular cygwin1.dll.

  This statement is unclear and confusing: is the MS linker trying to link a
cygwin DLL or a gcc-created .o?  Either way, it's impossible to tell from a
rough description whether this is just a manifestation of the same problem
above.  Compatibility with the MS tools has been much improved since this report
was filed, but if a problem can be demonstrated on up-to-date binutils we can
re-open this bug.

    cheers,
