Error when initializing multiple bit fields

[fafner2000]

Hello,

I found an issue when initializing multiple bit fields:

typedef struct
  {
  int field1,field2;
  unsigned int bit1:1,bit2:1;
  } some_struct;

static const some_struct S=
  {
  .field1=1,
  .field2=2,
  .bit1  =0,
  .bit2  =1,  // <- E1063: Missing operand
  };

It gives this error:
test.c(27): Error! E1063: Missing operand

This error doesn't depend on the presence of the trailing comma. Using -za99 doesn't change anything either. However, the error goes away when removing one of the bit field initializers (either bit1 or bit2). The error also goes away when using array-style initialization:

static const some_struct S={1,2,0,1};

I had a watch in the ISO/IEC 9899:1999 reference, section 6.7.8 , to make sure there wasn't some restriction on bit fields initialization, but didn't see anything special about them. Moreover, everything compiles fine with gcc.
