[Paul Eggert]

branch: master
commit c87a165040864919ae5ae23b97935300fa4ad119
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Update from Gnulib
    
    This incorporates:
    2020-02-21 largefile: remove _DARWIN_USE_64_BIT_INODE
    2020-02-21 Add ‘extern "C"’ to count-one-bits.h etc.
    * lib/count-leading-zeros.h, lib/count-one-bits.h:
    * lib/count-trailing-zeros.h, m4/largefile.m4: Copy from Gnulib.
