commit 908a9a6742b1010894fae2a4a9cf797b051d6c33
Author: Jay Satiro <address@hidden>
AuthorDate: Wed Jan 3 14:40:52 2018 -0500

    build: remove HAVE_LIMITS_H check
    
    .. because limits.h presence isn't optional, it's required by C89.
    
    Ref: http://port70.net/~nsz/c/c89/c89-draft.html#2.2.4.2
    
    Closes https://github.com/curl/curl/pull/2215
