@ -2,6 +2,14 @@ Thanks to everybody who's submitted changes and additions to Autoconf!
|
||||
I've incorporated many of them, and am still considering others for
|
||||
future releases -- but I didn't want to postpone this release indefinitely.
|
||||
|
||||
Caution: don't indiscriminantly rebuild configure scripts with
|
||||
Autoconf version 2. Some configure.in files need minor adjustments to

configure.in files, including those for GNU Emacs and the GNU C
|
||||
Library, need major changes because they relied on undocumented

||||

|
||||
updated configure.in files.

|
||||
Major changes in release 2.0:
