The two fns.c files are very different at this point; especially, their
exposing of the multibyte implementation to Lisp means the bulk of the code
that deals with strings is not useful to us. Remember also that most of the
functions that deal with sequences currently in our fns.c were moved there
from cl-seq.el, and there’s no prospect of GNU ever having those in C.

Accept bignums unambiguously in the syntax for object labels, lread.c.
src/ChangeLog addition:
2011-12-03 Aidan Kehoe <kehoea(a)parhasard.net>
* lread.c (read1):
Don't wrap when reading expressions that use bignums as object
labels, that can lead to ambiguity and it's not actually that hard
to use parse_integer() to avoid it.

2011-12-03 Aidan Kehoe <kehoea(a)parhasard.net>
* automated/lisp-reader-tests.el:
Check that integer object labels (using the #N=... syntax) treat
bignums as such, rather than as fixnums that have wrapped.
