Subject: tests: avoid spurious warnings about gl_sockets_startup
X-Git-Tag: v0.1~1219
X-Git-Url: http://erislabs.net/gitweb/?p=gnulib.git;a=commitdiff_plain;h=3888ec889ae709349cc7d9f7c1707dedbff2e130

tests: avoid spurious warnings about gl_sockets_startup

Fedora rawhide's gcc version 4.7.0 20120119 with -Wunused-value
would warn about every use of "gl_sockets_startup (SOCKETS_1_1);"
reporting a "statement with no effect".
