I believe you, but I'm definitely not sure that giving away by default this
important optimization for the sake of the few people playing with dlls is
the way to go for Cygwin. Maybe the fact that in so many years nobody
reported problems before should tell you something...

Anyway, you are probably right, you should first discuss the issue in the
Cygwin community and weight the various options. Then, if a change to the
configury localized to Cygwin will be in order rest assured that will be
very quickly approved. Thanks.
