/*
* Most of the API calls in here are, according to ADC, available since
21
* Mac OS 8.1. I don't think I used any Mac OS 9 or CarbonLib-specific
22
* functions. There might be one or two 8.5 calls, and perhaps when the
23
* ADC docs say "Available in Mac OS 8.1" they really mean "this works
24
25
* with System 6, but we don't want to hear about it at this point."
*
26
* IsAliasFile() showed up in Mac OS 8.5. You can duplicate this code with
27
* PBGetCatInfoSync(), which is an older API, if you hope the bits in the
28
* catalog info never change (which they won't for, say, Mac OS 8.1).

* If you want to use weak pointers and Gestalt, and choose the correct
* code to use during __PHYSFS_platformInit(), I'll accept a patch, but
* chances are, it wasn't worth the time it took to write this, let alone
* implement that.
