I've worked out a simple solution. In lib/gis/paths.c :

int G_lstat(const char *file_name, struct stat *buf)
{
#ifdef __MINGW32__
    return stat(file_name, buf);
#else
    return lstat(file_name, buf);
#endif
}

lstat(...) stats the link itself. Is there any reason why stat(...),
which follows a link instead, can't be used for both platforms?
