/**
* @file
* This header file is meant to help ensure that engines and
* infrastructure code do not make use of certain "forbidden" APIs, such
* as fopen(), setjmp(), etc.
* This is achieved by re-#defining various symbols to a "garbage"
* string which then triggers a compiler error.
*
* Backend files may #define FORBIDDEN_SYMBOL_ALLOW_ALL if they
* have to access functions like fopen, fread etc.
* Regular code, esp. code in engines/, should never do that.
* To ease transition, though, we allow re-enabling selected symbols
* in frontend code. However, this should only be used as a temporary
* measure. Especially new code should avoid this at all costs.
