4.4BSD snapshot (revision 8.1); add 1993 to copyright

Chris Torek's new version; speed up integer output, avoid quad ops

Peter McIlroy's version that's integrated with David Gay's work

Quad support in printf(3) family

delete CSH hacks -- csh no longer needs them

use isinf(3) and isnan(3) instead of rolling our own

Fix __STDC__ version of C-shell printf() to be more like Classic C version.

Add include files to get prototype declarations, and fix bugs found.

csh ugliness needs to pass sprintf on to regular stdio code

fix up gcc lint

NaN has a sign too

reinsert hp300 hack for Inf and NaN; add sparc to the list too

new stdio; renamed from doprnt.c. There was a trivial vfprintf.c
before, which called the doprnt code. It's in SCCS/S.vfprintf.c.

temporary fix to IEEE numbers modf can't handle. /* XXX */

new copyright notice

embedded assignments are dangerous; Auspex port found this one

%h is broken; "printf("%hd %hd\n", (short)1, (short)2);" doesn't
behave correctly. If this fix doesn't work, make sure your fix doesn't
sign extend on "%hu" and that "printf %hu -1" still works.

install approved copyright notice

minor optimizations

don't allow negative zero; ``printf("%.3f", (double)-0.00005);''
fix "% +5" and "%+ 5" to be identical, rename _cvt to cvt.

add D, O, U; completely redo the floating point

fix "printf("%4.1f\n", (double)0.0);"

fix %.60g to not add on precision digits

make sure we can write

various padding fixes from Chris
