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.
