 This is another low-priority 3.3 regression that was well hidden in GNAT.
 It's fixed in the mainline (3.4 20030430) with the new parser, even if the
 error message is far from decent:
 
 --------------------------
 class A<B>
 {
   int i;
 };
 --------------------------
 pr8078.cpp:1: error: expected unqualified-id
 pr8078.cpp:1: error: expected `,' or `;'
 
 
 On 2.95, the message was:
 
 pr8078.cpp:1: `B' was not declared in this scope
 pr8078.cpp:2: `A' is not a template
 pr8078.cpp:4: abstract declarator `{anonymous struct}' used as declaration
 pr8078.cpp:4: global anonymous unions must be declared static
 
 And the first half makes a lot of sense.
 
 If this bug is ever fixed in 3.3, or anyway before closing it, please check
 if the error message in 3.4 is improved. Otherwise, we can keep this as a
 low-priority 3.4 regression on error message text.
