[BZ #1060]
2006-01-10 Derek Price <derek@ximbiot.com> Paul Eggert <eggert@cs.ucla.edu> [BZ #1060] * posix/glob.c: Assume freestanding C89 compiler. Simplify cruft that may be replaced with GNULIB modules. Make no attempt to find 64-bit versions of file access functions directly when [!_LIBC]. Don't define GLOB_* macros here. (DIRENT_MUST_BE, DIRENT_MIGHT_BE_SYMLINK, DIRENT_MIGHT_BE_DIR): New macros to abstract dirent->d_type access. (GETPW_R_SIZE_MAX, GET_LOGIN_NAME_MAX): New macros to abstract sysconf access.
