Test case:

.macro macro1
LOCAL LC1
LOCAL LC2
LOCAL LCM
LC1:    tst r2, r2
LCM:    tst r0, r0
LC2:	tst r1, r1
.endm

.global _test_addc
_test_addc:

Generates the following error output with binutils 2.17 through CVS head:
./test.s: Assembler messages:
./test.s:15: Error: `LC2' was already used as parameter (or another local) name
./test.s:33: Error: symbol `.LL0017' is already defined

Last worked correctly in 2.16. Also tested (with the same results) built/hosted on i686-apple-darwin9.

This bug affects all targets, not just SH.
