  I dunno, but I see lotsa references to something called
'_cygwin_noncygwin_dll_entry@12' which sounds fairly suggestive.... then again,
you can't always tell what a subroutine does from the name.

  If the cygwin port of libtool passes two conflicting flags (-mno-cygwin and
-lcygwin) to the underlying compiler, then it's a cygwin problem, surely?

  Surely this is either a cygwin problem or an autotools problem?  (libtool
counts as part of autotools, doesn't it?)  It's not mingw's fault we've passed
bad args to the compiler......
