Defines

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.
