[PATCH, libgcc]: Avoid warning: array subscript is above array bounds when compiling crtstuff.c

[Uros Bizjak]

Hello!

Attached patch avoids a bunch of:

../../../gcc-svn/trunk/libgcc/crtstuff.c: In function 'frame_dummy':
../../../gcc-svn/trunk/libgcc/crtstuff.c:463:19: warning: array
subscript is above array bounds [-Warray-bounds]
   if (__JCR_LIST__[0])
                   ^

when compiling libgcc.

2014-03-08  Uros Bizjak  <ubiz...@gmail.com>

    * crtstuff.c (__JCR_LIST__): Declare as zero-length array.

Bootstrapped and regression tested on x86_64-pc-linux-gnu {,-m32}.

OK for mainline?

Uros.
