compiler error

[Wenjin Zheng]

Hi; 

I have included three files, one header, one .cpp file, one driver program
and one make file.  If you can make a fake library <libpq++.H> on your
system, I am pretty sure you can regenerate the error I got. But there might
be some kind of directory setup needed by the make file.  Thanks for the
help.

please keep this thread, and replies to it on the libstdc++ mailing

No, i can't tell what's up from any of your previous messages. I'm going
to need code. Sorry
