Subject: update for djgpp linker script

Hello,

It turns out that the ___EH* symbols aren't needed. The LONG(0) after 
.eh_fram* is needed for compatibility with the DJGPP version of gcc 
2.8.1, so it will have to stay for now.

Also note that .?tors. is hardcoded into gcc 2.95, so there is no choice 
on this.

ld/Changelog:

1999-08-19 Mark Elbrecht <snowball3@bigfoot.com>

* scripttempl/i386go32.sc (___EH_FRAME_BEGIN__, 
___EH_FRAME_END__): Delete.
  (_etext, _end): Move the semicolon inside the brace.

* scripttempl/i386go32.sc: Support the g++ attribute 'init_priority'.
  Add a period to link once section names.
