Subject: [PATCH] Suppress uninitialized-variable warning from less-bright
 compilers.

The type variable must get set on first iteration of the while loop,
but there are reasonably modern gcc versions that don't realize that.
Initialize it with a dummy value.  This undoes a removal of initialization
in commit 654809e770ce270c0bb9de726c5df1ab193d60f0.
