Subject: Avoid compiler warnings about uninitialised variables.
X-Git-Tag: v0.7.9~146
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6f1fc2655c5e4aea0b39e5d309a1cc4826f16d4e;p=pspp-builds.git

Avoid compiler warnings about uninitialised variables.

Some compilers produced warnings about possible use of
uninitialised variables (although such use was in fact not possible)
These warnings were harmless (perhaps even erroneous) but
it's no problem to avoid them.
