Subject: gcc/ 	* config/m68k/uclinux.h (STARTFILE_SPEC): Use Scrt1.o instead
 of 	crt1.o for shared libraries. 	(LIB_SPEC): Remove -elf2flt and
 -shared-lib-id 0 options. 	(LINK_SPEC): Map -mshared-library-id=N to
 -shared-lib-id N. 	Provide a default -shared-lib-id of 0. 
 (TARGET_OS_CPP_BUILTINS): Define __GXX_MERGED_TYPEINFO_NAMES=0 	for
 -mid-shared-library. 	(DRIVER_SELF_SPECS): Map unadorned PIC options to
 -msep-data. 	* config/m68k/t-uclinux (MULTILIB_OPTIONS): Add -msep-data and
 	-mid-shared-library multilibs. 	(MULTILIB_DIRNAMES): Update
 accordingly.
