[omniORB] Re: Alphalinux build failure

Looks like a compiler bug.

Before you look further, please try building omniORB 3.0 (from our cvs
server). At least you don't have to deal with the overly complex class
hierachy in Sun's IDL compiler fontend in 2.8.0.

Also, please check if the CPP macro __DECCXX is defined in your
compiler.
And the macro __DECCXX_VER is defined and is something greater than
60000000. There is quite a few #ifs in the code to cope with DEC
compiler
oddities.
