I've found a very simple solution for my problem.  The above suggestion
is not enough since the point in C++ is not to use any macros that can 
be avoided, especially with potentially conflicting names.  Since I 
do not want to suppress all the macros but only some known ones, I 
can simply wrap them into C++-style const char's and then #undef them.
I do this in a wrapper `config.hpp' header file which #includes 
the autoheader-generated `config.h'.  The other code only #includes
`config.hpp'.

That's all.
Thank you for your reply, Paul.
