Note that I found yesterday that if I accidently used a previous egcs
build to compile gcj (instead of using the default installed gcc) I
would have problems building some of the library files, jc1
complaining about some methods missing a return statement and later on
complaining about not being able to find certain file it couldn't
generate -- I'm pretty sure that java/io/ObjectInputStream was one of
them.
Before I realized my mistake, I found that this line
 BLOCK_EXPR_BODY (DECL_FUNCTION_BODY (mdecl)) = exit_block ();
in parse.y:end_artificial_method_body() wouldn't execute correctly and
instead of using exit_block() returned value, BLOCK_EXPR_BODY
(DECL_FUNCTION_BODY (mdecl)) would be set to NULL. I tried to use a
temporary variable, the bug went away and then I realized I was using
an old egcs build to compile jc1. I switched to the installed compiler
and the bug went away. Most likely a glitch in the previous egcs I
attempted to build.
Just make sure you're not in this situation.
