Subject: Remove "big endian" DNS section and RR data integer parser macros from
X-Git-Tag: upstream/1.10.0~1184
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d1ad89f943fa5abc98d8fd446d1869ac3bb363e3;p=platform%2Fupstream%2Fc-ares.git

Remove "big endian" DNS section and RR data integer parser macros from
ares_dns.h, which break c-ares on my Sparc64. Bit-wise operations in C
operate on logical values. And in any event the octets are already in
big-endian (aka network) byte order so they're being reversed (thus the
source of the breakage).
