Hi,
Just FYI about a problem I had with JDK 1.2 and JDK 1.3 with perl 5.6.1.
One needs to add "-DNEED_ENVIRON_DUP_FOR_MODIFY" when compiling perl 5.6.1 in order to work with JDK 1.2 and 1.3, at least on Solaris 2.6, 2.7, and 2.8.
Without this symbol, perl 5.6.1 can work with JDK 1.1.
What happened was that Java VM passes environment variables to perl and perl updates it directly. In JDK 1.1 the env. variables are in a read/write-able memory block. But in JDK 1.2/1.3 it's in a READ/EXEC memory block. Defining this symbol resolves this problem.
It might be useful to add this info. to perl's README file.
Thanks.
Kong
