Avoid duplicate declarations, assumptions about HAVE_BIGNUM, fns.c src/ChangeLog addition: 2011-01-02 Aidan Kehoe <kehoea@parhasard.net> * fns.c (FdeleteX, FremoveX, Fnsubstitute, Fsubstitute, syms_of_fns): Don't repeat the declaration and DEFSYMBOL() for Qnintersection in this file; don't assume that bignums are always available. Fixes some of the build problems the buildbot is showing me at the moment.
