Comment (by dimpase):
I'd like to reopen this ticket. The same applies to the rest of Sage
packages that create dlls with names clashing with dlls from Cygwin
packages (or perhaps other ones). Creating a dll which has the same name
as a Cygwin dll is asking for '''big''' trouble.
You might read on for details
[http://cygwin.com/ml/cygwin/2000-08/msg01128.html here in this long
thread].
In a nutshell, Windows is so dump that an application request to load a
dll with a certain name is handled by searching certain sub-directories,
in certain order. (Some of these subdirectories are actually specifies in
Windows registry). In some cases the order of sub-directores in the PATH
matters. I.e. when you link to a dlls, no full path information on the dll
is stored.
All you have is the PATH, registry entries, and few other things like
current directory, to play with.
