#define foo bar ,
nargs = -1, the `pattern' list is null, and the expansion is just
the replacement text. Nargs = 0 means a functionlike macro with no args,
e.g.,
#define getchar() getc (stdin) .
When there are args, the expansion is the replacement text with the
args squashed out, and the reflist is a list describing how to
build the output from the input: e.g., "3 chars, then the 1st arg,
then 9 chars, then the 3rd arg, then 0 chars, then the 2nd arg".
The chars here come from the expansion. Whatever is left of the
expansion after the last arg-occurrence is copied after that arg.
Note that the reflist can be arbitrarily long---
its length depends on the number of times the arguments appear in
the replacement text, not how many args there are. Example:
#define f(x) x+x+x+x+x+x+x would have replacement text "++++++" and
pattern list
{ (0, 1), (1, 1), (1, 1), ..., (1, 1), NULL }
