/* Use this file to list _all_ ENABLE() macros. Define the macros to be one of the following values:
* - "0" disables the feature by default. The feature can still be enabled for a specific port or environment.
* - "1" enables the feature by default. The feature can still be disabled for a specific port or environment.
*
* The feature defaults in this file are only taken into account if the (port specific) build system
* has not enabled or disabled a particular feature.
*
* Use this file to define ENABLE() macros only. Do not use this file to define USE() or macros !
*
* Only define a macro if it was not defined before - always check for !defined first.
*
* Keep the file sorted by the name of the defines. As an exception you can change the order
* to allow interdependencies between the default values.
*
* Below are a few potential commands to take advantage of this file running from the Source/WTF directory
*
* Get the list of feature defines: grep -o "ENABLE_\(\w\+\)" wtf/FeatureDefines.h | sort | uniq
* Get the list of features enabled by default for a PLATFORM(XXX): gcc -E -dM -I. -DWTF_PLATFORM_XXX "wtf/Platform.h" | grep "ENABLE_\w\+ 1" | cut -d' ' -f2 | sort
