* 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.
