Possbile patch for compilation errors re possibly uninitialized variables at -Og

[Louis Krupp <louis dot krupp at zoho dot com>]

I tried to build the trunk using:

BOOT_CFLAGS='-g -Og' CFLAGS_FOR_TARGET='-g -Og' CFLAGS_FOR_BUILD='-g -Og'

I got a number of compilation warnings -- promoted to errors -- about possibly uninitialized variables.

I have what I believe is a decent patch that initializes those variables and which I've tested at revision 256030. The errors go away for -Og, as well as for -O0.

When I run make with no arguments and then run "make check", I get the same test failures as I do in an unmodified and identically built reference tree at the same revision.

I've attached the patch along with a list of tentative ChangeLog entries and their respective directories. I can adjust the format of those entries as needed.

Being able to build with -Og or -O0 would make my life easier.
