Not quite... but gcj did build GENERIC statments with nothing but a
VAR_DECL.  Such statements were stripped by the gimplifier, having no side
effects.  So the outcome was legal GIMPLE, but not what was intended.

Perhaps the gimplifier could do better when dealing with VAR_DECL
statements that are really expressions (i.e. nested in a non-void
BIND_EXPR that is also used as the RHS of an assignment).
