 *
 * Miscellaneous switches:
 *
 * A number of macros affect a variety of minor aspects of ICU.
 * Most of them used to be defined elsewhere (e.g., in utypes.h or platform.h)
 * and moved here to make them easier to find.
 *
 * Switches for excluding parts of ICU library code modules:
 *
 * Changing these macros allows building partial, smaller libraries for special purposes.
 * By default, all modules are built.
 * The switches are fairly coarse, controlling large modules.
 * Basic services cannot be turned off.
 *
 * Building with any of these options does not guarantee that the
 * ICU build process will completely work. It is recommended that
 * the ICU libraries and data be built using the normal build.
 * At that time you should remove the data used by those services.
 * After building the ICU data library, you should rebuild the ICU
 * libraries with these switches customized to your needs.
