While I was silencing some warnings about narrowing conversions, which
was https://gcc.gnu.org/ml/gcc-patches/2016-08/msg02129.html (for
reference), I also silenced some warnings from -Wmaybe-uninitialized
in combine.c and varasm.c while I was at it. I took the easy way out
and simply initialized the variables; there might possibly be a better
way to go about it, I don't know...
Thanks,
Eric Gallager
