/* PR17544 Incorrect -Wunreachable-code warning
Origin: sebor@roguewave.com
G++ appends a "return 0;" when finishing a function, but it was not
given a source location. The gimplifier thinks a return statement
needs a locus so it would add one, making the compiler generated code
visible to the unreachable code warning. */
