Log Message:
update to gerbv-1.0.2

Changes are:
* Removed all build support for GTK1.
* Dino Ghilardi fixed log.c (the last reminder of GTK1) so
  log windows popup don't crash gerbv anymore.
* Dan McMahill added the GCC4 patch.
* Renamed stack_t to macro_stack_t to support darwin/MacOS X
  pointed out by Daniel Mack.
* Changed build system to suit new autoconf/automake versions.
  Caused gerbv not to find init.scm.
* Fixed a bug so gerbv can handle negative coordinates when using
  trailing zeroes.
* Better checking of return values for errors.
* Use setlocale explicit so your locale doesn't screw up sscanf
  and strtod to use comma (,) instead of dot (.).
* For distributions there is a new directory called desktop, where
  gerbv.desktop and gerbv.png is stored for desktop settings.
  Submitted to Debian bug list from Vassilis Pandis for Ubuntu.
