gEDA: New covered-0.2pre3 release available

[Trevor Williams <trevorw@charter.net>]

Release covered-0.2pre3 made.  It has been quite a while since a release 
has been made
which has been due to a particularly tricky bug that was found with 
non-blocking
assignments.  This bug generated bad coverage information (this is 
considered very bad!)
This release contains bug fixes and development documentation updates.  
If no more problems
are found with this release, I will get the 0.2 release made very soon.  
The following
is a list of the changes for this release.

 - Fixes to line.c and toggle.c to provide better cross-platform support.
 - Lots of updates to the development documentation.
 - Fixed bug with properly handling hierarchical references in expressions.
 - Fixing bug with single-bit parameter handling (caused a diagnostic 
miscompare
   between Linux and Irix OS's).
 - Fixed non-blocking assignment bug.  This bug affected the order of 
execution in
   Covered's simulator which resulted in bad coverage information being 
generated.
 - Fixed bugs in divide, mod, left shift, right shift and some other 
expression types
   to avoid converting variables that have unknown values to integers 
(which results
   in Covered errors at run-time).

The list of changes is short, but the changes made are very necessary to 
getting reliable
coverage numbers from Covered.  Please get a copy of this version and 
test it out so that
we can get the stable 0.2 release made ASAP.

Thanks,
Trevor Williams
