RE: Linux/390: Compilation Errors in veo38.cpp and veo964.cpp

Daniel,

These patches didn't correct the problem with veo964.cpp.  Now, I'm seeing
veo964.cpp fast
veo964.cpp: In function `void ShowAndRemoveNiErrorTrace(int)':
veo964.cpp:100: request for member `asCharp' in `line', which is of
   non-aggregate type `char[81]'
veo964.cpp:106: cannot pass objects of non-POD type `class tsp00_Pathc'\
 through
   `...'

1. can we move such questions to
sapdb.sources?(http://listserv.sap.com/mailman/listinfo/sapdb.sources)

2. patches follow, explanation at the end for those interested

Explanation:

param_stack->lpbuf->msg.mtype and line are C++ objects that are designed to
look like enum and char [] respectively. They have the proper conversion
operators for the common uses. But of course when passed to a varargs list,
the compiler doesn't know that the conversion has to be called. gcc 3.2
seems to be more strict in that regard, but it was in error all along.
