utah rcsid 1.6 87/11/29 20:31:47: Remove isitfloat() -- this was broken,
yylex() now handles this properly. Also delete useless SPRECC ifdef.

utah rcsid 1.5 87/07/17 19:21:48: (1) Replaced SCONV code in clocal() with
VAX version. (2) Deleted the 'float percolation' code in clocal() -- it's
simply wrong. (3) Deleted the QUEST case in cloc

utah rcsid 1.5 87/07/17 19:21:48: (1) Replaced SCONV code in clocal() with
VAX version. (2) Deleted the 'float percolation' code in clocal() -- it's
simply wrong. (3) Deleted the QUEST case in clocal() which hacks around
the funny trees created by the deleted 'float percolation'. (4) Added 'if
(nerrors) return' to vfdzero(). (5) Changed %X to %lx in incode() and
vfdzero(). (6) Cleaned up some comments, to make this code more easily
diffable with the VAX version.

some lint tidbits.

utah rcsid 1.3 87/04/17 21:32:02: Oops -- we still want to clobber constant
conversions...

utah rcsid 1.2 87/04/17 03:31:22: Let optim2() handle conversion
optimizations for variables.
