This struct should have "const char*" and you can remove the cast below.

This says you can't use the ## operator, on the token [ and smexec.
(The strong nuclear force does not help you to concatenate them. :-)

You need to work on strings, and not use stringify of paste_tokens:

#define NAME_STRING "[" stringify(TARGETNAME) "]"
I suppose not calling paste_tokens would also work:
#define NAME_STRING stringify([TARGETNAME])
