size_t C_MB_CUR_MAX() { return MB_CUR_MAX; }

int has_cur_term() { return cur_term != NULL; }
Port common.{h,cpp} to Rust Most of it is duplicated, hence untested. Functions like mbrtowc are not exposed by the libc crate, so declare them ourselves. Since we don't know the definition of C macros, add two big hacks to make this work: 1. Replace MB_LEN_MAX and mbstate_t with values (resp types) that should be large enough for any implementation. 2. Detect the definition of MB_CUR_MAX in the build script. This requires more changes for each new libc. We could also use this approach for 1. Additionally, this commit brings a small behavior change to read_unquoted_escape(): we cannot decode surrogate code points like \UDE01 into a Rust char, so use � (\UFFFD, replacement character) instead. Previously, we added such code points to a wcstring; looks like they were ignored when printed. 2023-03-26 23:23:05 +08:00			`#include <stdlib.h>`
