Subject: Add a few initializations to quiet compiler warnings.
X-Git-Url: https://git.cworth.org/git?p=scherzo;a=commitdiff_plain;h=68466b09f103fd72188afe18f8d01f11f2163fde

Add a few initializations to quiet compiler warnings.

My manual analysis says that none of these are strictly necessary,
(the various conditionals currently ensure that none of the variables
are ever used uninitialized). But "gcc -O2" likes to complain, so
these initializations keep it quiet.
