Re: CHICKEN 6 and win32 support

bit one Q/ in FFI API manual we have info: "
C_c_string <https://wiki.call-cc.org/man/6/C%20interface#c_c_string>

[C function] char* C_c_string (C_word string)


These macros and functions can be used to convert Scheme data objects back
to C data. Note that C_c_string() returns a pointer to the character buffer
of the actual Scheme object and is not zero-terminated."

but in runtime.c:11973+ we have
11973   C_char *topname = (C_char *)C_c_string(entry);
11974   C_char *mname = (C_char *)C_c_string(name);
11975   C_char *tmp;
11976   int tmp_len = 0;
11977
11978   if((handle = C_dlopen(mname, dlopen_flags)) != NULL) {
11979     if((p = C_dlsym(handle, topname)) == NULL) {
...
like  C_c_string returns zero terminated strings we pass strat to C_dlopen,
C_dlsym...
And CSI is not loading shared .so on msys2. questionable?
