generate argz.c and argz.in.h from glibc sources * config/argz.mk: New file, with rules to generate the two files. * modules/argz (Depends-on): Add mempcpy, stpcpy, strndup and strnlen. Suggested by David Lutterkort. * m4/argz.m4: Require AC_C_RESTRICT. Check only for the existence of one function, argz_replace, since it seems to have been added most recently. Also, remove the side effect of defining HAVE_ARGZ_* symbols. * lib/argz.c: Now generated directly from glibc sources, rather than imported from libtool. Includes the following additional functions: argz_extract, argz_create, argz_delete, str_append, argz_replace. * lib/argz.in.h: Likewise. * config/srclist.txt: Reflect that argz* files are no longer pulled from libtool.
