3 June 2007: Overview of changes in 2.19.3
==========================================
* Small API change. get_proclist returns pid_t instead of unsigned
  for consistency.
* linux:
  - fixed an typo bug in open_files.
  - got rid of useless glibtop_init_s calls.
* Enable example build by defaut.
* Dropped G_GNUC_INTERNAL attributes no longer needed.
  This will please people trying to implement G_GNUC macro with a non
  GNU Compiler.
