Subject: FreeTDM: gcc-4.6 fix (-Wunused-but-set)
X-Git-Tag: v1.2-rc1~118^2~6^2~20
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9cceb8e62ca2473df5cb564d97b0b404c96212e4;p=thirdparty%2Ffreeswitch.git

FreeTDM: gcc-4.6 fix (-Wunused-but-set)

ftmod_wanpipe.c:
	Remove myerrno variable in wanpipe_read(),
	snprintf does not set errno (according to the manpage),
	so no need to save it (without even using it later).
