Changelog,v 1.4 1995/08/17 23:22:58 explorer Exp

03-Mar-95	0.0.1	explorer

Not generally released.

26-Mar-95	0.0.2	explorer

	Not generally released.

	Many fixes from Jelle van Zeijl <jvzeijl@isous1.estec.esa.nl>,
	including:

	- src/libray/libcommon/blob.c:
	  the prototype of qsort() on Ultrix has "void const *" as type
	  for the parameters to the compare function. The compiler gives
	  an error on that.  So I need a "voidconststar" type in common.h
	  to have a proper definition.

	- the definition of MKDEP in various Makefiles is not used.
	  'makedepend' is used instead.

	- add "make depend" to README

	- Ultrix' signal() has an "int" as parameter. I vaguely remember
	  another auto-config script that has a test for the type of
	  signal(). That should be used instead of the "#ifdef ultrix"
	  I've used now.

	- index() still is a problem. I now patched the rle include file
	  to *not* define index() as strchr(). But Ultrix doesn't have a
	  prototype in string.h (which is symlink to strings.h :-( ).

	- #define of GeomFlameCreate() was wrong (compared to all other
	  Create() functions).

	- other small changes

	Also, with prompting from Jelle van Zeijl:

	- check for stdlib.h rather than stdlib in configure.in

	- fixed --with-rlelib checking.

05-Apr-95	0.0.3	Jelle van Zeijl
	- added ability to animate eyep, lookp, and up. Motion blurring does
	  not work (yet). Changes are not applied to raypaint.
	- added ability to animate variables via extended "define"
	- added TimeGet() and FrameGet() as counterparts of TimeSet() and
	  FrameSet()
	- added more intuitive interfaces to string comparison (streq(),
	  streql())
	- added conditional expressions: <, <=, >, >=, ==, !=, ?:
	- added boolean expressions: &&, ||
	- a minus ("-") is no longer a valid character in a identifier name
	  (because it clashed with the minus operator in expressions). Also
	  renamed tSTRING to tIDENT to better reflect its meaning.
	- extended the "print" definition to allow for strings to be printed
	  and for more than one argument to be printed.
	- added lint target to Makefile.in but only problems are in raypaint
	- some layout changes (TABs vs spaces)

17-Aug-95	0.0.4	Michael Graff
	- Fixed an error in the configure script (missing && in one place)
	- Added a quick and dirty replacement for strerror() for those who
	  were missing it.  It just prints out the error number right now.
	- Added a replacement for strdup() because some of the code will
	  begin using it rather than strsave() or whatever it uses now.
