Hm, isn't that pretty much expected? Cygwin's infrastructure tries to be
unixoid, so it's not surprising that the toolchain doesn't require such
strange things? Otherwise even larger amounts of unix software wouldn't
run, right?
I am pretty sure halfway recent versions of mingw can be made to behave
similarly, but I don't really see the advantage in doing so, to the
contrary even.

My ld(1)'s manpage has three screen's worth of details... Most of it
seems to be on http://www.freebsd.org/cgi/man.cgi?query=ld&sektion=1

It's essentially elf like shared library linking in pe-coff through
dirty tricks.
