Hallo Abraham,

Ah, I didn't saw this yet.

Great.

One cannot symlink DLL's on Windows.  You can hardlink or copy it, but it
should not be neccessary, one can use a symlink to link the importlibs
libxerces-c.a -> libxerces-c-2.1.0.a so you can use -lxerces-c at the
linkline when compiling your own application.  Anyway the linker should
pick libxerces-c-2.1.0.dll as rt.
BTW, there is some consensus that cygwin DLL's should be prefixed with
'cyg' instead of 'lib' to differentiate them from native Windows libs.

It is really important to point this out!  C++ code built with GCC3 is not
binary compatible with code compiled with GCC2.
