In the BSDI kernel there are many parameter defined structures.  With
gcc v1 the following function will compile and "work".

mytest(parameter_struct_variable)
     register struct args {
       char  a;
       int   b;
     } *parameter_struct_variable;
{
  struct args {
	char a;
	int  c;	
  } local_struct_variable;
  
  local_struct_variable.a = parameter_struct_variable->a; /* OK */
  local_struct_variable.c = parameter_struct_variable->b; /* BAD */
}

version 2 of gcc produces:

/usr/local/bin/gcc -c foo.c
foo.c: In function `mytest':
foo.c:5: warning: structure defined inside parms
foo.c:7: redefinition of `struct args'
foo.c:13: structure has no member named `b'

where vesion 1 of gcc does not care about this.  Could someone please
let us know why this functionality of gcc has changed from version 1
and version 2.

(Personally, I think that version 2 does the correct thing with
 redefining the structure, since parameters and local variables
 really should be at the same scope.)
