Subject: toke.c - silence maybe-uninitialized warning on gcc 12
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This silences the following (bogus) warning:

toke.c:12104:24: warning:
    ‘b’ may be used uninitialized [-Wmaybe-uninitialized]

It won't be used unitialized, but there is no reason not to initialize
it to shut up the warning on gcc-12

Fixes Github Issue #20816
