Work around some portability problems with symlinks. * Makefile.in (GNULIB_MODULES): Add lstat, readlink, symlink. * configure.in (lstat, HAVE_LSTAT): Remove special hack. * lib/lstat.c, lib/readlink.c, lib/stat.c, lib/symlink.c: * m4/dos.m4, m4/lstat.m4, m4/readlink.m4, m4/stat.m4, m4/symlink.m4: New files, automatically generated from gnulib. * aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk: * lib/stdlib.in.h, m4/gl-comp.m4, m4/stdlib_h.m4: Regenerate. 2011-02-22 Paul Eggert <eggert@cs.ucla.edu> [src/ChangeLog] Work around some portability problems with symlinks. * fileio.c (Frename_file, Fmake_symbolic_link, Ffile_symlink_p): Simplify the code by assuming that the readlink and symlink calls exist, even if they always fail on this host. (Ffile_readable_p): Likewise, for fifos. * config.in: Regenerate.
