   This patch was put on the list about a month ago, and it is essential
   for partial linkage with C++ and i386/PE.

   Please scream if you don't want me to check this in...

	   * coffcode.h (coff_write_object_contents): Don't call
	   coff_write_symbols if we already have a nonzero
	   obj_raw_syment_count.

You can put it in, but please add a comment explaining why checking
obj_raw_syment_count is correct.  I was hesitating to approve it
earlier because I hoped to verify for myself that it was the right
test.  But you might as well go ahead if you are sure.
