[cfg-branch] Fix one warning

[Andreas Jaeger]

Honza,

I just got:

stage1/xgcc -Bstage1/ -B/opt/gcc/cfg/i686-pc-linux-gnu/bin/ -c  -DIN_GCC    -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long  -DHAVE_CONFIG_H    -I. -I. -I/cvs/gcc-cfg-branch/gcc -I/cvs/gcc-cfg-branch/gcc/. -I/cvs/gcc-cfg-branch/gcc/config -I/cvs/gcc-cfg-branch/gcc/../include /cvs/gcc-cfg-branch/gcc/cfgcleanup.c -o cfgcleanup.o
/cvs/gcc-cfg-branch/gcc/cfgcleanup.c: In function `thread_jump':
/cvs/gcc-cfg-branch/gcc/cfgcleanup.c:323: warning: traditional C lacks a separate namespace for labels, identifier `failed' conflicts
/cvs/gcc-cfg-branch/gcc/cfgcleanup.c: In function `try_forward_edges':
/cvs/gcc-cfg-branch/gcc/cfgcleanup.c:338: warning: `threaded_edge' might be used uninitialized in this function

The first warning has been fixed with the appended patch (committed as
obvious) and the second warning looks right.  Can you check the usage
of 'threaded_edge', something wrong is happening here.

	* cfgcleanup.c (thread_jump): Rename label fail to avoid warning.
