 That's more or less what I'm doing now. But the problem is that I was porting all
 code that used the other way and was working for years.
 As this code is an example of a library I'm affraid a lot of people will be using the
 old approach and failing.
 I got really confused when the code break without any apparent reason.

 BTW: What I use now is a macro, it expands to getline for gcc (libstdc++ v2 and v3)
 but I was forced to expand it to a function call for Borland compilers where the
 getline fails to extract the trailing newline.
