How to compile postgres JDBC in win95 cygwin-b20

Hello,

I'm new to postgres, and i was wondering on how to compile postgres JDBC in cygwin-b20. when i execute the make command in the src/interfaces/jdbc, i got the following errors:

BASH.EXE-2.02$make
make $(java makeVersion)
javac postgresql/Connection.java
postgresql\Connection.java:7: Class postgresql.Field not found in import.
import postgresql.Field;
^
postgresql\Connection.java:8: Package postgresql.fastpath not found in import.
import postgresql.fastpath.*;
^
postgresql\Connection.java:9: Package postgresql.largeobject not found in import.
import postgresql.largeobject.*;
^
postgresql\Connection.java:10: Package postgresql.util not found in import.
import postgresql.util.*;
^
4 errors
make[1]: *** [postgresql/Connection.class] Error 1
make: *** [all] Error 2

I'm using JDK 1.2.2 SE and JSDK 2.0. What could have been the mistake?

Thanks!
