undefined reference to `debugstr'

[ryandesign]

In my app I'm trying to use debugstr (which is like DebugStr but accepts C strings instead of Pascal strings) but although I've included MacTypes.h where it's declared (in Universal Interfaces from MPW 3.5) I'm getting a link error:

main.cpp:677: undefined reference to `debugstr'
collect2: error: ld returned 1 exit status

Is this a glue function that would need to be implemented in libretro/glue.c? If so, are the other standard Mac OS functions that are known to be missing from libretro at this time?

This issue is similar to #19 though that was about missing newlib functions whereas this is about missing standard Mac OS functions.
