If you remove the __thumb__ part, then you will get an assembler error.
palantir:2025$ arm-linux-gnueabi-as UnwindCurrent.s
UnwindCurrent.s: Assembler messages:
UnwindCurrent.s:1504: Error: PC not allowed in register list -- `stmia

This instruction is not a valid thumb instruction. It is a valid arm
instruction, but deprecated. The assembler gives an error because you
are in thumb mode. Since you already have a __thumb__ version of the
macro, you can put a ".thumb" directive at the end of the asm, after
the orr instruction, to manually switch back into thumb mode.
