Binutils 2.47 fails to build with warning 'exp.X_op' may be used uninitialized

[R. Diez]

Hi all:

Binutils 2.47 fails to build with this error message:

-------8<-------8<-------

   CCLD     as-new
/home/rdiez/blah.../binutils-2.47/gas/config/tc-arm.c: In function 'parse_immediate.constprop':

Is this a known issue? The older Binutils 2.46.1 builds fine in the same setup.
