Subject: network: Don't redefine error codes if they already exist in errno.h
X-Git-Tag: n1.1-dev~9^2~1075
X-Git-Url: http://git.ffmpeg.org/gitweb/ffmpeg.git/commitdiff_plain/4b1b1449d95b3567d055fc410a1db137c811229c

network: Don't redefine error codes if they already exist in errno.h

Since the errno.h values don't match the error codes that winsock
returns, map the winsock error codes to the errno ones, to make
sure explicit checks against AVERROR(x) match.
