OK, here we go. This patch is for modules that you maintain or
co-maintain.
I removed uses of AC_TRY_{CPP,COMPILE,LINK,RUN}, replacing it with
the m4-semantic equivalent, double-m4-quoted, code. In a couple of
cases, I have improved the quoting of the surrounding code, too.
This means your code may not work with Autoconf older than 2.55
(sic! 7 years old), even if it did so before.
I have tested the patch by running
gnulib-tool --with-tests --test
and ensuring that the resulting configure script has differences only in
white space and within comments.
OK to apply?
Thanks,
Ralf
Remove obsolete macros in Jim's modules.
* 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.
