I am compiling a program on a aix with an oslevel -r equal 5100-04.
We've got problem running this program using a machine with oslevel
5100-03 (btw in std::stream).
I suppose there is a backward compability so that what works on -03
works on -04, but it there upward compability between maintenance
level ?
With your experience is the first thing is to upgrade the os ?

Thank's for your answers.

That is a C++ runtime issue, which is irrelevant of the OS level.
You will need a level of xlC.aix50.rte that at least _matches_
the one on your build machine.

Forward compatibility is not guaranteed.
