I reached what seems to be a limitation in the numlber of LC_COLLATE collating-elements.

I was trying to build a dz_BT locale (Dzongkha language, Buthan);
the sorting rules are quite special, as for example nexy to <ka> entry are words starting with prefix attached to ka radical, eg: <da>-<ka>, <ba>-<ka> etc, come just after words starting with <ka>, and not with words starting with <da>, <ba>, etc.
Said otherwise, the base collating elements are the 30 base letters, plus 103 prefix-radical collating elements.
Now, it is even more complex that that; some letter sequences are prefix-radical or not depending on what follows them; eg for <da>-<ga> it is a prefix if followed with <ga>, <nga>, <da>,... but not otherwise.
That is, it is needed to define collating elements comprising of the prefix element and the next char, which are then sorted as a digraph; eg:
collating-element <rad-ga-d-ga> from "<U0F51><U0F42><U0F42>"
...
<rad-ga-d-ga>  "<TIB-GA-R_D><TIB-GA>";....

That mens there are a lot of collating-elements to define; 303 in total.
But ifI use more than 265 the locale doesn't compile (localedef just runs forever taking 90% of cpu ressources doing nothing); while if I comment some of them to have no more than 265 in use, then it compiles nicely.

I attach the preliminary dz_BT locale I was working on; some entries are commented with %%%% (four percent signs), so that the file can compile; but to have the rules complete, all those lines commented out with "%%%%" should be enabled as well.
