// TESTBAIL
// This test used to be a test for a bug BAIL found.
// That bug is now fixed so I've granted BAIL the pleasure of being a test for
// the correct priority ordering of hook managers based on their version.
/*
THE PROBLEM:
Old hook funcs don't work right when you combine override returns and recalls.
THE SOLUTION:
Always use a new hook func when possible. For this, hook funcs have to be able to say
" HELLO I'M NEW! "
This file tests that functionality.
How it works:
testbail.cpp compiles with old version of sourcehook.h.
It sets everything up, adds a hook on a function
Then testbail2.cpp which has the new version adds a hook on the same function and
does a recall and overrides the value in it.
