[jed-users] Deprecated autoconf macros

[Rafael Laboissière <rafael@xxxxxxxxxx>]

Dear JED developers,

In the Debian package for JED, we are applying the patch attached to this 
message, which copes with some deprecated autoconf macros in 
autoconf/configure.ac and autoconf/aclocal.m4.

Please, consider integrating this change in the next release tarball.

Best,

Rafael Laboissière

Description: Replace deprecated autoconf macros
 The obsolete autoconf macro AC_AIX is a platform-specific subset of
 AC_USE_SYSTEM_EXTENSIONS.
 .
 The obsolete AC_HELP_STRINGS has been replaced by AS_HELP_STRING.
 .
 AC_CONFIG_HEADER is an older macro that is less funcional than
 AC_CONFIG_HEADERS.
 .
 The obsolete macro AC_ISC_POSIX adds -lcposix to output variable LIBS
 if necessary for Posix facilities. Sun dropped support for the obsolete INTERACTIVE
 Systems Corporation Unix on 2006-07-23. New programs need not use
 this macro.
 .
