Howdy,
A recent bootstrap on i686-pc-linux-gnu reported the following
warning:
/home/kraai/src/gcc/gcc/dwarf2out.c: In function `output_call_frame_info':
/home/kraai/src/gcc/gcc/dwarf2out.c:1719: warning: int format, long unsigned int arg (arg 4)
The attached patch fixes this problem by casting the label
identifier number to an unsigned int before outputing it, just as
is done when sprintfing the name into a string. The resulting
compiler bootstrapped on i686-pc-linux-gnu (with one fewer
warning).
