Watch out, here.  The bzlib and zlib installed on cygwin have the 
following characteristics:
   a) link to the DLL by default (so you have to use -static and 
-DZLIB_STATIC etc if you want to link statically)
   b) since DLL's are not allowed to have unresolved symbols when they 
are built, cygz.dll and cygbz21.dll are "prelinked" to cygwin1.dll.  So 
linking setup.exe dynamically to the "system" zlib and bzlib is out.
   c) So, you have to do the wacky -DZLIB_STATIC stuff...
Blech.
