master 75dfc1e870 1/2: Port module_bignum_count_max to strict C

[Paul Eggert]

branch: master
commit 75dfc1e8706d994bd7b18a24360847fd12bd5af0
Author: Paul Eggert <eggert@cs.ucla.edu>
Commit: Paul Eggert <eggert@cs.ucla.edu>

    Port module_bignum_count_max to strict C
    
    * src/emacs-module.c (module_bignum_count_max): Make
    this a macro, not an enum, since it might not fit into
    int as C99 requires.
