|
||||
* configure.in: Remove --with-elf and --enable-bounded options.
|
||||
Dont set base_machine for ia64. More non-ELF conditions removed.
|
||||
Remove testing and setting of leading underscore information.
|
||||
* config.make.in (build-bounded): Set to no.
|
||||
* config.h.in: Remove NO_UNDERSCORES entry.
|
||||
* include/libc-symbols.h: Don't define HAVE_WEAK_SYMBOLS. ELF has
|
||||
them.
|
||||
* csu/start.c: Remove !NO_UNDERSCORE code.
