What about this version then:
(and it is probably not correct anymore)
istream & operator>>(istream & is, lyxstring & str)
{
typedef istream istream_type;
typedef int int_type;
typedef std::streambuf streambuf_type;
typedef string string_type;
typedef string::size_type size_type;
size_type extracted = 0;
str.erase();
std::streamsize w = is.width();
size_type n;
n = w > 0 ? static_cast<size_type>(w) : str.max_size();
int_type const eof = EOF;
streambuf_type * sb = is.rdbuf();
int_type c = sb->sgetc();
while (extracted < n
&& c != eof && !isspace(c)) {
str += c;
++extracted;
c = sb->snextc();
}
if (c == eof)
is.setstate(std::ios::eofbit);
is.width(0);
if (!extracted)
is.setstate(std::ios::failbit);
return is;
}
