Suppress uninitialized-variable warning from less-bright compilers.

tglsfdc · tglsfdc · commit 60ff5de22aa4 · 2015-02-28T10:46:10.000-05:00
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 654809e.
