Duh.  Of course I know that it is possible to load conflicting versions of
the Cygwin DLL.  I guess that means that Windows doesn't just blindly use
DLLs of the same name (unless specially instructed to do so).

That means that the (so far hypothetical) DLL problems should be
solvable by keeping the DLLs in the same directory as the executables.
