| 2 | ; explicitly specified prototypes, inserting a new function if the old one |
| 3 | ; didn't exist. This caused there to be two external memcpy functions in |
| 4 | ; this testcase for example, which caused the CBE to mangle one, screwing |
| 5 | ; everything up. :( Test that this does not happen anymore. |
