That is a windows problem. The XFree libraries are in fact versioned.
(libXaw.so.6.1 vs libXaw.so.7.0)

Hm, after all I would rename the the -2 version of the library. Existing
programs might link to libXft.dll and expect version 1 of the abi. New
programs must then be linked against libXft2.dll if they use the version
2 abi. OTOH the linker will use libXft.dll if -lXft was used.

Hm, recalling from Memory:
The version number is always defined in the makefile. So instead of
of doing Libraryname.so.Libraryname (from linux) we could do
Libraryname$(patsubst ...).dll

Or even better,
#ifdef CygwinArchitecture
#define LibraryName Xft2
#else
#define LibraryName Xft
#endif

Maybe this should be wrapped to NoShlibVersions or similar. I think 
this is a problem for OS/2 too.
