(rtld-version-installed-name): New, default as ld-$(version).so. * Makefile (install): Call `$(common-objpfx)elf/ldconfig -d' only if $(cross-compiling) is no and $(build-shared) is yes. * Makerules (make-shlib-link): New macro.

(+link): New for static linking. ($(slibdir)/$(rtld-version-installed-name)): New. ($(slibdir)/$(rtld-installed-name)): Depend on $(slibdir)/$(rtld-version-installed-name) and use $(make-shlib-link) for symlink. * sunrpc/xdr.c (xdr_string): Return FALSE if sp == NULL while XDR_ENCODE. * sysdeps/unix/sysv/linux/a.out.h: Use #include_next for glibc internals. * sysdeps/unix/sysv/linux/configure.in (libc_cv_rootsbindir): New, set to "/sbin" if "$prefix" == "/usr". Tue Jan 21 13:38:39 1997 Ulrich Drepper <drepper@cygnus.com> * Makefile (distribute): Add glibcbug.in. Reported by Philip Blundell <pjb27@cam.ac.uk>. * elf/Makefile ($(objpfx)trusted-dirs.h): Create elf/ subdir in build directory if necessary. Reported by marcus@shannon.sysc.pdx.edu (Marcus G.

|
|
The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
|
|
of `struct option' terminated by an element containing a name which is
|
|
zero.
|
|
|
|
The field `has_arg' is:
|
|
no_argument (or 0) if the option does not take an argument,
|
|
required_argument (or 1) if the option requires an argument,
|
|
optional_argument (or 2) if the option takes an optional argument.
|
|
|
|
If the field `flag' is not NULL, it points to a variable that is set
|
|
to the value given in the field `val' when the option is found, but
|
|
left unchanged if the option is not found.
|
|
|
|
To have a long-named option do something other than set an `int' to
|
|
a compiled-in constant, such as set a value from `optarg', set the
|
|
option's `flag' field to zero and its `val' field to a nonzero
|
|
value (the equivalent single-letter option character, if there is
|
|
one). For long options that have a zero `flag' field, `getopt'
|
|
returns the contents of the `val' field. */
