I did that already since years in RHIDE and it worked perfectly.

Now I have reviewed the latest gdb sources and saw that the
problem really exists and I'm not happy about this change.

So my question is now: Why does exist there a file called libgdb.texi
in the doc directory? I know now, that this file describes only an
imaginary library which does not exist, but if there exists such a
description of a libgdb the maintainer of gdb should think also a little
bit about that people, who did the hard job to integrate the gdb functionality
also in other programs even when it is not the described libgdb but a
lib with the same goal.

This is not the best but only for now the shortest solution, since it
will force me to change every time my duplicated code when something
related to it will change in the future in the gdb sources.

BTW: There is not only an describtion of the imaginary libgdb, but there
is also a target in the Makefile which is called libgdb-files, which creates
a file containing all the names of the object files for the libgdb. So if, main.o
is not part of it, but main.o conatains code which is refered by other
files, than this is a bug.
