[jacorb-developer] JacORB 3.4 documentation - 25.1 IDL - intrinsic preprocessor symbol does not seem to work as described

[Timothy Astle]

My choice of terminology and explanation waspoor.

I'm generating sources for the ImplRepo.pidl from TAO.  I use JacORB to 
make calls into the TAO Implementation Repository for administration 
tasks.  The ImplRepo.idl needs to include the orb.idl, so I supply the 
JacORB orb.idl (because it works).

If I don't provide the cited additional compiler arguments to explicitly 
define the preprocessor symbols, the source generation fails.

_PRE_3_0_COMPILER_ -> Keeps the compiler from complaining that it 
doesn't know what "module" is on the module CORBA line in the orb.idl
JACORB -> avoided the comma problem / abstract issue

When it failed the first time, I decided to use -U because the 
documentation said the preprocessor symbols were intrinsic, but it 
didn't change the behaviour.  Setting them allowed the source to be 
compiled.

I'm probably missing something, or a few things :)
