This is a summary of the changes I made with respect to Martin Sperl's
release of wxxt-1.66d.

* kept libwx_xt and libwx_xtwidgets as separate libraries instead of
  creating a single, large libwx

* added src/xt-glx and src/xt-thread additional libraries, generated
  when configuring with `--with-opengl' and `--with-threads' respectively

* GLCanvas is replaced with wxGLCanvas (incompatible change), which
  works well with non-default visuals, private colormaps and Mesa-2.6

* added disabling/enabling of cancellation in wxThread for POSIX threads;
  also there is doc++-structured documentation in APP_thread.h now

* fixed makefiles and setup/* scripts to not depend on GNU find or
  old shells (e.g. bash-2.0 rejects `do (...) done')

* fixed sharedIrix and sharedLinux to include major version number in
  the soname

* improved `configure' for Irix 5.x and 6.x

* fixed focus bug in src/xt-widgets/Common.w (surfaced with WindowMaker)

* cleanup DEV_dc.h for use with glibc-2

* added colour allocation in private colourmaps

* closed memory leak in wxWindowDC::DrawBitmap8()

* switched from bcopy() to memcpy() in src/xt/IPC_{client,socket}.cpp

* fixed `distrib_base' target in the main Makefile
