Hi! The following patch silences two warnings in the mep-elf target, fixing the config-list.mk build:
First one:

This is actually a misbehavior of current GCC, the code itself looks 100% okay
to me. Shall I report that as a bug, too?
Second one:

This patch should fix it. Okay to apply?

* config/mep/mep-pragma.c (mep_pragma_coprocessor_subclass): Rework
to silence warning.
* config/mep/mep.c (VECTOR_TYPE_P): Remove duplicate definition.
