[Emacs-diffs] master 32d8dba: Remove some tautological comparisons involving rlim_t

[Philipp Stephani]

branch: master
commit 32d8dba625fc50ccbe28e35afcf1f0529d611e00
Author: Philipp Stephani <address@hidden>
Commit: Philipp Stephani <address@hidden>

    Remove some tautological comparisons involving rlim_t
    
    Clang on macOS warns about these with -Wtautological-compare.  POSIX
    guarantees that rlim_t is
    unsigned (cf.
    
http://pubs.opengroup.org/onlinepubs/009695399/basedefs/sys/resource.h.html),
    so these resource limits can never be negative.
    
    * src/emacs.c (main): Remove tautological comparisons.
