Larry is correct. You are not. Problems do occur with multiple copies of
Cygwin1.dll on a system. We see it here all the time.
Cygwin relies on a shared memory segment and when there's more than one
copy of the DLL on a given system, eventually a second one will get loaded,
try to initialize itself and either fail or interfere with the one that's
already loaded and initialized.
If you want to do this, it's no skin off our nose, but DON'T recommend that
others do so.

been using cygwin for quite a long time and have had no probs with this.
Even when you upgrade the cygwin package and install it, it will ask you if
you would like to remove the old dll from the system32 folder. Then you
could just do a copy of the new one. That said you could just make a copy of
it to the folder where your executable is it will work there to. Thanks for

Anyone who decides they want to do this is free to but it will invalidate
their installation and make it unstable. Future problems they may run into
as a result will not be seriously entertained by this list (assuming said
persons post to this list for help in those cases) until cygwin1.dll is
put back where setup installed it. For anyone wondering, copying
cygwin1.dll to this directory or any other carries the same warning.
