  Replace uses of obsolete autoconf macros in Jim's modules.
  
  The Autoconf macros AC_TRY_CPP, AC_TRY_COMPILE, AC_TRY_LINK and
  AC_TRY_RUN have been obsolete since Autoconf 2.55, and each use
  can evoke a warning from autoconf when run with -Wobsolete
  enabled.  They were declared obsolete for good reasons (see
  the `AC_FOO_IFELSE vs AC_TRY_FOO' node in the Autoconf manual,
  recently renamed to `AC_ACT_IFELSE vs AC_TRY_ACT'), and we
  should not continue using the deprecated macros.
  
  * m4/d-type.m4 (gl_CHECK_TYPE_STRUCT_DIRENT_D_TYPE): Replace
  obsolete Autoconf macros with modern counterparts.
  * m4/dirfd.m4 (gl_FUNC_DIRFD): Likewise.
  * m4/dos.m4 (gl_AC_DOS): Likewise.
  * m4/fpending.m4 (gl_FUNC_FPENDING): Likewise.
  * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Likewise.
  * m4/getloadavg.m4 (gl_PREREQ_GETLOADAVG): Likewise.
  * m4/jm-winsz1.m4 (gl_WINSIZE_IN_PTEM): Likewise.
  * m4/link-follow.m4 (gl_AC_FUNC_LINK_FOLLOWS_SYMLINK): Likewise.
  * m4/ls-mntd-fs.m4 (gl_LIST_MOUNTED_FILE_SYSTEMS): Likewise.
  * m4/mkdir-slash.m4 (gl_FUNC_MKDIR_TRAILING_SLASH): Likewise.
  * m4/mode_t.m4 (gl_PROMOTED_TYPE_MODE_T): Likewise.
  * m4/rename-dest-slash.m4 (gl_FUNC_RENAME_TRAILING_DEST_SLASH):
  Likewise.
