* Playing-field leveller for Build
|
|
* by Jonathon Fowler
|
|
*
|
|
* A note about this:
|
|
* 1. There is some kind of problem somewhere in the functions below because
|
|
* compiling with __compat_h_macrodef__ disabled makes stupid things happen.
|
|
* 2. The functions below, aside from the ones which aren't trivial, were never
|
|
* really intended to be used for anything except tracking anr removing ties
|
|
* to the standard C library from games. Using the Bxx versions of functions
|
|
* means we can redefine those names to link up with different runtime library
|
|
* names.
