/*
* notes: by srl295
* - When in NODE_HAVE_SMALL_ICU mode, ICU is linked against "stub" (null) data
* ( stubdata/libicudata.a ) containing nothing, no data, and it's also
* linked against a "small" data file which the SMALL_ICUDATA_ENTRY_POINT
* macro names. That's the "english+root" data.
*
* If icu_data_path is non-null, the user has provided a path and we assume
* it goes somewhere useful. We set that path in ICU, and exit.
* If icu_data_path is null, they haven't set a path and we want the
* "english+root" data. We call
* udata_setCommonData(SMALL_ICUDATA_ENTRY_POINT,...)
* to load up the english+root data.
*
* - when NOT in NODE_HAVE_SMALL_ICU mode, ICU is linked directly with its full
* data. All of the variables and command line options for changing data at
* runtime are disabled, as they wouldn't fully override the internal data.
* See: http://bugs.icu-project.org/trac/ticket/10924
