fewer than before;) but prozac isn't giving any false positives.

the beginning of unititialized var detection. first victim: functions.

--undefined-function-warning is now --no-undefined-function-warning and

segging.
pr_imm.c:
o rename int_val to integer_val
o support integer constants, converting to float when needed.
pr_lex.c:
o magic number death and support quaternions and integers in type_size[]
qc-lex.l
o rename int_val to integer_val
o support quaternion and integer type keywords
qc-parse.y:

o use binary_expr instead of new_binary_expr for local initialized
variables
builtins.c:
o rename int_val to integer_val
o fix most (all?) of the INT related FIXMEs
defs.qc:
o use integer instead of float where it makes sense
main.c:
o read_result is now integer rather than float
main.qc:
o float -> integer where appropriate
o new test for int const to float arg

expr.h:

add label_expr prototype
expr.c:
ex_statement nukage
correct new_expr's decl
add label_expr to ease label creation
don't crash when printing a null expression (bare return)
qc-parse.y:
estatement_t nukage
statement statements and statement_block are type expr
generate `expressions' for statements
a full parse tree for each function is now generated. there are several
special expression opcodes for statements:
d done \
r return -> unary: expression to return or null
i if binary: evaluated expression, destination label
n ifnot binary: evaluated expression, destination label
c call binary: function def, args (expr list, rev order)
s state binary: frame const, function def
g goto unary: destination label
l label unary: label number
in a top level expression, l (label) defines the label, otherwise it is a
reference.
