GAS 2.11.1 doesn't work for sh-hitachi-coff

No time to dig into, sorry. (I'll leave on vacations really soon now ...)

Why is .file in COFF illegal and why did gas 2.10.1 accept it ?

obj-coff.c has

void
c_dot_file_symbol (filename)
     char *filename;
{
  symbolS *symbolP;

  symbolP = symbol_new (".file",
			SEG_DEBUG,
			0,
			&zero_address_frag);
...

I'll try and block out the two lines in tc-sh.c
