Fixed so that "1/pivot" is rejected as a number, rather than dividing

This is not a good fix, but I need it now for some existing code. The
parser ought to be restructured not to compute the real part until it
is known that the imaginary part is valid, e.g.
(string->number "1/2+3") => #F
(string->number "1/0+3") => error
(string->number "1/0-transition") => error
There is a similar problem with exponent calculation:
(string->number "
1e9999e1") => error
(string->number "
1e99999999e1") => `hangs' in bignum primitives
Of course, the difficulty with these non-numbers is probably the
reason behind R4RS's restriction on valid identifiers. That is pretty
feeble, since I don't recall R4RS saying that STRING->NUMBER is
allowed to signal an error. Note that the current code would work
fine in a lazy language, so a few DELAYs and FORCEs might be the most

The following change in how WIN32 graphics devices are flushed gives

If graphics buffering is enabled, then a GRAPHICS-FLUSH operation

can clear and draw without an asynchronous redraw operation copying

This is not quite double-buffering since forced redisplay during the

The previous change to make the output with '(ABSOLUTE <N> ...)

digits introduced problems with NORMAL rounded and ENGINEERING
formatted output. All NORMAL rounded output for numbers of the form
ddd.ff were being output as "000.". Some numbers formatted with
'(ABSOLUTE <N> ENGINEERING) looked like "000e-3".
This has been fixed by
(1) setting the cutoff for NORMAL rounded numbers to be a value that
will allow the digit production to run to completion
(flo:significand-digits - 2).
(2) adding special cases in the output procedures to deal with empty
digit strings.
Currently:
Zero still prints as "0." by the initial sign/infinity/NaN dispatch.
Rounded output in NORMAL style for numbers with no significant digits
prints as "0." or "-0.".
Rounded output in SCIENTIFIC / ENGINEERING style for numbers with no
significant digits prints as "0eE" or "-0eE", e.g. "-0e3".
It might be preferable to keep "0." distinguished for zero, but I'm

more `zero' than "0.", and ".0" implies a small magnitude.)

Fix bug: end index in substring is exclusive, not inclusive.

Changed error for non-root access to a warning, so at least we can get
a .crf file output.

Changed FIXNUM->FLONUM back to using cast.
I don't understand why the last change was made -- the cast should
have worked, since arg_fixnum() returns a long. Perhaps I blew it and
tested it on 8.0 and just happen to have fixed the real problem at
about the same time.

A hack: Introduced macro
case_TC_FIXNUMs
for generating case labels for selecting fixnums, whether there are
one or two typecodes. This tidies up the support in the 8.0 sources
for eitehr case, and allows more files to be shared between 7.4 and
8.0
