silence GCC, eg:

55 | #define ISC_TL INDIC_SYLLABIC_CATEGORY_TONE_LETTER /* 7 chars; Tone_Letter */

Avoid undefined-behavior
...
If a struct had (because it's a union) sizeof that is larger than the null_size,
we were providing only null_size bytes for its Null object. We know we'd never
access beyond that, but is undefined-behavior nonetheless according to the
standard.
The alternative fix would have required use of flexible-arrays, which are not
standard and have their own issues in various compiler. We've discussed that
extensively in the follow Mozilla issue (currently locked; I've asked that it
be opened):

improve comments on Hebrew ccc 18 & 19

improve comments to reflect that:
ccc 18 includes both "flavors" of qamats: qamats [gadol] and qamats qatan
ccc 19 includes both "flavors" of holam: holam [not haser for vav] and holam haser for vav
This code and its comments may have been written before these code points were added to Unicode.
I.e. originally, these comments may have been complete, but they may have become incomplete in the meantime.
