I found a good reference to the problem noted above. It can be reviewed
at the URL
<http://docs.hp.com/en/B3901-90003/ch02s01.html>
under the section titled Spreading Source Code Across Multiple Lines.
Again, this issue is with regard to the C Language, and since Net-SNMP is
written in the C Language, the MFD scripts ought to generate C Language
code, not C++ Language code. I did check Stroustrup, and the relevant
section in his book The C++ Programming Language, second edition,
section r.16.1, page 607, Phases of Preprocessing, paragraph 7:
[Adjacent string literals are concatenated.]
I will send a section of code produced by the MFD script to demonstrate
the specific issue in mib2c generated code.
