This usually means you have the wrong version of autoconf.  I keep a
build of the FSF release tarballs of autoconf 2.59 and appropriate
automake versions to use when regenerating files in GDB or GCC.

That's not what it is trying to say - you have to commit the change.
But you don't have to post it to the list, since it's not useful for
people to read it.

Take a look at the java.exp and ada.exp support code.  You'll want a
pascal.exp.  You can avoid target_compile entirely if that's easiest,
although I've made it work  with a completely non-GCC compiler in the
past.  All you really need is the bit at the bottom that handles
moving the source and executable around and calling remote_exec.

I can help you with it if you need.  The TCL bits are confusing.
