One possible work-around for this issue would be to re-define the ISR API so 
that, e.g., the SIGNAL macro expands to two independent expressions:

1.) a asm(" .global vector_xx\nvector_xx .equ 
speaking_function_name_entry_label");
2.) a function declaration with a speaking name.

After this change, the deprecated macro should be readily useable.
