This is a list of all the tokens that are being used in a #ifdef or #ifndef in a .cpp or .h file, except for .h files, where tokens used as #ifndef FOO_H or #ifndef FOO_H_ are excluded, as these are almost certainly just include guards. The list is current as of r52922.
No additional filtering has been performed as of yet; some tokens are defined by a platform, while others may not actually be used. Additionally, defined symbols not used in #ifndef or #ifdef are not included at all here.
Defines to be set by/for backends
The following defines are meant to be defined by backend authors, typically
in configure (or a custom Makefile). Usually these enable or disable certain
features in ScummVM. E.g. a low-powered port might turn off some features
that won't work on the target device anyway, to free up some memory.

audio/mixer.cpp
|
Normally, Audio::Mixer produces 16bit signed interleaved (left before right) stereo data. With this define set, it changes the channel order (first right channel, then left).

|
Makes ScummVM return to the launcher instead of exiting (ideal for ports that take a long while to load). Note that this is a big HACK, in particular, it allows one to return to the launcher from engines / games which do not support this normally for a good reason (such as not being reentrant).
