1220 | directory' include searchpath entries. | |
1221 | (struct file_name_list): Add *alloc pointer for the sake of | |

1237 | duplicate code from the search_start selection logic. | |
1238 | (cpp_reader_init): Initialize pfile->actual_dirs. | |
1239 | ||
1240 | Remove definition of HOST_WIDE_INT. Change calls | |
1241 | to cpp_parse_escape to match changes in cppexp.c (note | |
1242 | hardcoded MASK, which is safe since this is the source | |
1243 | character set). | |
1244 | ||
1245 | * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c | |
1246 | to handle wide character constants in #if directives. The | |
1247 | function now returns a HOST_WIDE_INT, and takes a third | |
1248 | argument which is a binary mask for all legal values (0x00ff | |
1249 | for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define | |
1250 | MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of | |
1251 | cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c] | |
