Strange behavior of gcc-3.1

[Agust Karlsson <Gusti at pallas dot dk>]

I have just upgraded my gcc from 2.96 (RedHat 7.2 distribution) to 3.1
(compiled from source with prefix=/usr)
Oddly, things that did work OK before seem to fail now.

I have included an example with the error messages I get.
Does someone have a clou on what's happened???


----------------------------------------------------------------------------
----------
struct Data {
  int var[10];
};

void f1( int *param)
{ int p;
  p = param[ 7]; 
  if (( 7<=p) && (p<= 14)) 
    Data.var[ 7] = p;
//  p = param[ 9];             // any of these two lines
//  if (( 5<=p) && (p<= 30))   // can provoke the error in the next line 
    Data.var[ 9] = p;
}

// ---------------------------

// how to declare and use a packed enum ?

typedef enum { v11=1, v12=2 } e1 __attribute__ ((packed));
void g1( e1 par) {}

enum e2 { v21=1, v22=2} __attribute ((packed));
void g2( e2 par) {}
----------------------------------------------------------------------------
--------------------------------------------

This is the output from g++ -c test.cpp :

test.cpp: In function `void f1(int*)':
test.cpp:9: parse error before `.' token
test.cpp: At global scope:
test.cpp:20: non-local function `void g1(<anonymous enum>)' uses anonymous
type
test.cpp:22: semicolon missing after declaration of `e2'
