Declare the union somewhere within the scope you need (global if you
must), and use a comma operator if there's no cleaner way to express things.

	union { int i; float f; } intfloat;
	target = ( intfloat.i = messy()->expr , intfloat.f ) ;

Remember the parentheses around the comma expression.
I tried this, and lint didn't even mind.
