Re: The recent glibc breakage (dynamically linking with libthreads)

[Alfred M. Szmidt]

The patch that I sent is quite wrong.  The proper place to define
DL_ARGV_NOT_RELRO is not in sysdeps/mach/hurd/i386/dl-machine.h, but
in sysdeps/mach/hurd/dl-sysdeps.h (it needs to be included by
ldosdefs.h).  Now _dl_argv ends up in .bss, and not in .rel.ro; as it
should be.
