Date: Fri, 14 Oct 1994 22:57:12 +0000
Subject: [PATCH] * Makefile.in (ALL_EMULATIONS): Add ei386nw.o and eppcnw.o.  
 (ei386nw.c, eppcnw.c): New targets.

* config/{i386,ppc}-nw.mt, emulparams/{i386,ppc}nw.sh,
  scripttmpl/nw.sc: New files, for i386 and powerpc netware.

* configure.in: Changed netware ld_target name to be {i386,ppc}-nw
  instead of {i386,ppc}-elf.

* configure.in (sparc*-*-netware): Removed.  There is no such
  thing anymore.
