I've just compiled oleo-1.2.1 on a NeXT running NeXTSTEP 3.0. Things that
seem noteworthy:

	- oleo uses CPU time like crazy even when no user interaction
          takes place. Looks like it is waiting for keyboard input in raw
	  mode a little bit too busy (just a guess).

	- the header file dependencies in Makefile.in look like some
	  `make depend' generated stuff. It's not a good idea to have
	  this in Makefile.in, which should be as generic as possible.
	  I noticed this because Makefile.in contains a direct dependency to
	  /usr/include/ctype.h which NeXTSTEP 3.0 does not have (it's
	  in /NextDeveloper/Headers/ansi/ctype.h).
	  This is of course trivial to fix, but nevertheless annoying.

	- when a floating point value is entered into a cell it gets
	  reformatted to use the maximum number of possible decimal
	  digits, e.g. one enters 42.1 and the cell gets filled with
	  something like 42.10000000001.
	  I know that this is due to a bug (or non-POSIX conformance)
	  in NeXTs sprintf formatting code and therefore not strictly
	  a bug in oleo, however, I suspect there may be more platforms
	  that have this problem so maybe oleo should do it's own formatting,
	  at least when it comes to screen output.
