Nice to hear, everything works now.

I also fixed the libtool problem of rxtx.

There was another issue not being listed in any bug report I fixed as
well: classpath-native is seemingly miscompiled by Debian's gcc 4.3.2.
At least I got strange behavior with [VM]File.exists(). It returned true
while there is no directory. The problem disappeared when I added a
printf() into the native code. So I expected GCC is optimizing in a
wrong way here. Declaring the respective variable 'volatile' made the
error go away, too.

Ah yes. All this trouble was causing spurious ".class file could not be
created" error messages printed by ecj when compiling rxtx.

I have seen the same error in other recipes too and hope that they are
fixed as well now.

Regards
Robert
