| 29 | // We don't use the C-locale masks defined in mingw/include/ctype.h | |
| 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. | |
