Porting to gcc 4.3

[mathieu]

Hello there,

  I am working on a debian package that need to compile on testing
which is using gcc 4.3.

http://gcc.gnu.org/gcc-4.3/porting_to.html

  Is pretty nicely written, and I was able to solve most of my issue.
There remaining ones are related to the use of ostrstream. I have not
found any document showing how to quickly move the code. AFAIK this is
non-trivial to port to ostringstream (allocation is not handled the
same way).

  Any suggestion ?

Thanks
