Subject: Fix spurious output in configure
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=489ec6b2fcd09621a2ac146298193a8231810e60;p=thirdparty%2Fpostgresql.git

Fix spurious output in configure

If sizeof off_t is 4, then configure will print a line saying just "0"
after the test.  This is the output of the following "expr" command.
If we are using expr just for the exit code, the output should be sent
to /dev/null, as is done elsewhere.
