V: hot reload not working on macOS

[hachi8833]

V version:
V 0.1.25 c2f22a4
OS:
macOS Catalina
What did you do?

Performed v -cg -live message.v under examples/hot_reload.

What did you expect to see?

Compiles without errors.

• I remember compiling the sample worked on Mac last year, around December.
• Compiling the sample on Ubuntu Linux env still works without any errors/warnings.

What did you see instead?

not only on osx, the same error (_STR function ) occurs on windows too for some examples
