I have no idea.
Cygwin now attempts to relocate its cygwin heap immediately after the
DLL. If another DLL loads but up against the Cygwin DLL then it
will cause problems.
Like many things in cygwin this is a compromise over many distasteful
options.
If it truly offends people then I assume that everyone will rush over
to cygheap.cc and find another solution to the problem.
If it means that auto-import-base doesn't work then that's really
a shame. I don't know what to say beyond that except live with
it. I'm not going to fix binutils.
For me, it's a compromise of Windows XP whining over auto-import-base
whining. So far the XP whiners win by a longshot.
