Heres what I include:
#include "includes.h"
#include "winbindd.h"
which is the same as "wbinfo.c"
using the following:
CPPFLAGS=-I/home/mike/work/samba/source
-I/home/mike/work/samba/source/include -I/home/mike/work/samba/source/ubiqx
-I/home/mike/work/samba/source/smbwrapper
I had to setup all those include dirs to get it to compile.
As C is cool, but when I compile as C++ I see the following:
--------------------------------------------------
g++ -I/home/mike/work/samba/source -I/home/mike/work/samba/source/include

-I /home/mike/work/cda/comm -I/usr/local/pgsql/include -I/usr/include/pgsql
-c -o agent.o agent.cc

If I omit the #include of the includes.h file, i get:

Perhaps some doco on what are the right set of header files needed and what
other libs are needed would be useful.
