Subject: 	Merge changes from progressive for dos x udi:
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d1b785153e6d914551aa78cd3adbb24c008d4c77;p=binutils-gdb.git

	Merge changes from progressive for dos x udi:
	* Makefile.in (udi2go32.o): add rule to build this file
	* 29k-share/udi/udi2go32.c: new file
	* config/a29k/a29k-udi.mt: add udi2go32.o
	* 29k-share/udi/{udr.c, udip2soc.c}: #ifdef out the entire file
	  if __GO32__ is defined.  What a hack.
