compiling the examples

Hi,

How do i make the examples in postgresql-7.3.3/src/test/examples/?
It seems that just typing make doesn't link to the libpq library. Where
should I start make?

Just typing make gives the following output:
# make
gcc -O2 -Wall -Wmissing-prototypes -Wmissing-declarations
-I../../../src/interfaces/libpq -I../../../src/include
-Wl,-rpath,/usr/local/pgsql/lib testlibpq.c -o testlibpq
