Sorry for being late on this...
Short version: Problem solved, reason remains a mystery.
Hmm. get_progname() should be getting linked into the createdb executable by way of libpgport.a from the src/port/ directory. Can you look at the build process in src/port/ and src/bin/scripts/ and try to see what went wrong? The only idea that comes to mind is that a wrong (old) copy of libpgport got picked up somehow, but seeing that we don't install it, it's not clear how there could be an old copy anywhere.
Long version:
Before I wrote the first mail, I checked two times whether I could reproduce this behaviour. First, I made a "make distclean" before compiling and checking again. Then, I even removed the whole thing and started from zero.
Both times I got this error message.
In an effort to answer your question above, I started again from scratch on the same machine... And you guess it - the checks went through.
I don't know what happend that day.
I'm sorry if I raised some dust!
Best regards,
Wolfgang
