Comment (by Erik Schnetter):

I recommend two further changes for safety:

• Add parentheses around fn_call
• Add a do { } while (0) construct around the current if construct. I’m not sure whether the current if construct is working as expected if it is followed directly by an else keyword.

Approved.
