Compatibility 2.95.2 -> 3.0.2

[Hultman, Sten]

Hi !

I am currently trying to port an application from HP-UX10.20 and gcc2.95.2
to HP-UX11.00 using gcc3.0.2.

As you can se in my enclosed listing a come across a large number of
compatibility problems. 

I suppose this could be cured by including the correct combination of
include files ?  Is there possibly any "compatibility flags" that have
to be set ? I have studied the documentation as well as all entries in
this forum without finding  the answer.
I would very much appreciate any hint about where to find the solution.
I can't be alone with these problems.

Regards
Sten Hultman
