30 | // because those masks do not conform to the requirements of 22.2.1. | |
31 | // In particular, a separate 'print' bitmask does not exist (isprint(c) | |
32 | // relies on a combination of flags) and the '_ALPHA' mask is also a | |
33 | // combination of simple bitmasks. Thus, we define libstdc++-specific | |
34 | // masks here, based on the generic masks, and the corresponding | |
35 | // classic_table in ctype_noninline.h. | |
