[Paul Eggert]

branch: master
commit 9d11f127f15cc4dafcdb825dcfc6e495d729a069
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    --with-wide-int is a no-op on 64-bit hosts
    
    * configure.ac: Clarify wording for --with-wide-int help.
    * src/pdumper.c (dump_vectorlike_generic):
    Do the eassert even if --with-wide-int was specified unnecessarily.
