Subject: configure: Ensure the version always has 3 parts in PSPP_CHECK_XGETTEXT.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3acd86a8d90595a63babe88c4c7c2cb1fd5465cf;p=pspp

configure: Ensure the version always has 3 parts in PSPP_CHECK_XGETTEXT.

Makes configure succeed on Debian for me, where "xgettext --version" prints
0.21 as the version.
