jdbc driver compilation under linux

Hello,

I'm trying to compile JDBC interface for PostgreSQL 6.3 using JDK 1.1.6
under Linux 2.0.34.
I took JDBC sources from PostgreSQL 6.3 distribution.
I also tried with earlier versions of JDK. The problem is that jar
produces 'segmentation fault'.

Here's the whole compilation dump:

javac postgresql/CallableStatement.java
javac postgresql/geometric/PGbox.java
javac postgresql/geometric/PGcircle.java
javac postgresql/geometric/PGlseg.java
javac postgresql/geometric/PGpath.java
javac postgresql/geometric/PGpolygon.java
jar -c0f postgresql.jar $(find postgresql -name "*.class" -print)
SIGSEGV   11*  segmentation violation
        stackbase=0xbffff360, stackpointer=0xbffff264

I also tried to compile it on earlier version of JDK (1.1.3) with no
results.

Can you help me with solving this problem? I'd like to start practising
java&jdbc programming, but it's hard to do it without driver installed.

Thanks in advance.
