[Bug c/41974] New: gcc/genautomata.c, gcc/builtins.c: 4 * set but not used

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I just had a look at the source code of
gcc version 4.5 snapshot 20091105 and I notice that

1.

for source code file gcc/genautomata.c, function
check_regexp_units_distribution,
local variable cycle2 is set but unused.

This looks like a candidate for deletion to me.

2.

for source code file gcc/builtins.c, function expand_builtin_mathfn,
local variable before_call looks set but not used.

Another candidate for deletion.

3.

same source code file gcc/builtins.c, function expand_powi, local variable
"val" is set but not used.

4.

same source code file gcc/builtins.c, function expand_builtin_expect, local
variable
"c" is set but not used.
