canonicalize-lgpl: fix glibc bug with trailing slash Consolidate the m4 macros into a single file, since both modules now have to worry about replacing canonicalize_file_name on buggy glibc. * m4/canonicalize-lgpl.m4: Move contents... * m4/canonicalize.m4: ...here. (gl_CANONICALIZE_LGPL): Factor realpath check... (gl_FUNC_REALPATH_WORKS): ...into new macro. Enhance to catch glibc 2.3.5 bug, fixed 2005-04-27. (gl_FUNC_CANONICALIZE_FILENAME_MODE): Use it. (gl_PREREQ_CANONICALIZE_LGPL): Inline... (gl_CANONICALIZE_LGPL_SEPARATE): ...into this macro. * modules/canonicalize-lgpl (Files): Manage file rename. * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Provide default. * modules/stdlib (Makefile.am): Substitute witness. * lib/stdlib.in.h (canonicalize_file_name): Declare if replacement is needed. * lib/canonicalize-lgpl.c: Also compile if canonicalize_file_name replacement is required. * lib/canonicalize.c (canonicalize_file_name): Likewise. * doc/glibc-functions/canonicalize_file_name.texi (canonicalize_file_name): Document this. * doc/posix-functions/realpath.texi (realpath): Likewise.
