v1.5

* tcllauncher no longer generates or references a shared library.

* tcllauncher now is linked against the thread library to avoid
  deadlocking if Tcl is built with threads

* Sync Makefile.in with TEA 3.9; clean up the generation of the object
  file and the executable

* tcllauncher-support.tcl is now macro-substituted from
  tcllauncher-support.tcl.in to get package and version right every time
