Subject: perl-module: Avoid VERSION redefinition warning from compiler.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?p=pspp;a=commitdiff_plain;h=b795616d57f3a26415aee6a30edfd00ef004e31b

perl-module: Avoid VERSION redefinition warning from compiler.

If the PSPP version includes a suffix like "-pre1", then Perl will strip
that suffix from the version it passes to the compiler using -DVERSION=...,
and <config.h> will re-define it with the full version string.  This causes
a warning.

This change avoids the warning.  I am not yet aware of a new problem that
it causes.
