You either need to add

enable_shared = no

to Makefile.ultrix4, or inform Makefile.shlib about how to build shared
libraries.

If you're using GCC then configure with --enable-depend to build
dependencies, so you don't have to do make clean everytime.

Since there will be more unnecessary inclusions the next time somebody
touches a file, the ultimately better strategy might be to add such a
wrapper manually.

See src/bin/psql/Makefile for examples of linking in helper .o files.

Better to explicitly include sys/ipc.h again where it's needed.

There's

AC_CHECK_LIB(dl, main)

which does what you want, but you need to give your linker a hint where to
find it. See configure --with-libraries.

Maybe the stuff under

src/tools/pginclude/

helps.
