[libcxx] [regex] Use distinct __regex_word on NetBSD

Authored by mgorny on Dec 13 2018, 9:08 AM.



NetBSD defines character classes up to 0x2000. Use 0x8000 as a safe
__regex_word that hopefully will not collide with other values
in the foreseeable future.

Where and what defines 0x2000, what header and what symbol name?

OK, I got it:

#define _CTYPE_Q 0x2000 /* Phonogram */

from /usr/include/sys/ctype_bits.h

I propose to mention the symbol name in the description and the header. In the description is worth to mention the filename of this definition.
