Details:

I tried building from SVN trunk r5973 with gcj (GCC) 4.1.2 20070302
(prerelease) (4.1.2-1mdv2007.1), which is the current official/update release
on Mandriva 2007.  It has trouble with e.g. choosing the correct `execute'
method to call in my example file, attached to this report.

This causes r5973 to break like:

./configure --with-gcj && make
...
CLASSPATH=../..:./../..:$CLASSPATH gcj -C -d ../.. -g AbstractFormat.java
AbstractSequence.java ...
PrintConsumer.java: In class 'gnu.lists.PrintConsumer':
PrintConsumer.java: In method
'gnu.lists.PrintConsumer.write(java.lang.CharSequence,int,int)':
PrintConsumer.java:74: error: Can't find method
‘write(Ljava/lang/String;II)’ in type ‘gnu.lists.PrintConsumer’.
Candidates are:
  'gnu.lists.PrintConsumer.write(java.lang.CharSequence,int,int)' in
'gnu.lists.PrintConsumer'
  'java.io.PrintWriter.write(java.lang.String,int,int)' in
'java.io.PrintWriter'.
      write((String) csq, start, end);

I worked around it here by putting super.write instead.

I asked in irc.oftc.net/#gcj and at least gcj (GCC) 4.1.3 20070518
(prerelease) (Debian 4.1.2-8) supports the construct correctly, so there may
be too small a subset of compilers to justify changing it in SVN.
