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. * m4/rename.m4 (gl_FUNC_RENAME): Likewise. * m4/rmdir-errno.m4 (gl_FUNC_RMDIR_NOTEMPTY): Likewise. * m4/rpmatch.m4 (gl_PREREQ_RPMATCH): Likewise. * m4/st_dm_mode.m4 (AC_STRUCT_ST_DM_MODE): Likewise. * m4/stat-time.m4 (gl_STAT_TIME): Likewise. * m4/utimes-null.m4 (gl_FUNC_UTIMES_NULL): Likewise.
