Hi,
this fixes a -Wshadow=local warning in the FOR_EACH_ALIAS macro
that happens when it is used in lto/lto-partition.c in a nested
block.
For now to keep the patch simple, using the fact that the ALIAS
parameter is always a simple name, concatenate _iter_ to make
the loop variable a reserved name.
Bootstrapped and reg-tested on x86_64-pc-linux-gnu.
Is it OK for trunk?
Thanks
Bernd.
