Yes, it will work without disabling the warning. However, I
don't allow code with warnings to ship.

I've never seen anything like that before.

You're getting those errors after patching
mspgcc/gcc/gcc-3.3/gcc/config/msp430/* and building gccd 3.2.3?

I don't remember having any such issues when I made the
changes. In my copy of the mspgcc soruces, it's declared in
msp430-protos.h, which is apparently visible from within in
msp430.c:
$ grep -r unique_section mspgcc/gcc/gcc-3.3
mspgcc/gcc/gcc-3.3/gcc/config/msp430/msp430-protos.h:extern void
unique_section PARAMS ((tree decl, int reloc));
mspgcc/gcc/gcc-3.3/gcc/config/msp430/msp430.c:unique_section (decl, reloc)
mspgcc/gcc/gcc-3.3/gcc/config/msp430/msp430.h:#define UNIQUE_SECTION(DECL,
RELOC) unique_section (DECL, RELOC)
I just verified msp430-protos.h against CVS, and it's
unchanged. You must have a broken source tree.
