From: Paul Eggert Date: Sun, 1 Sep 2002 08:25:09 +0000 (+0000) Subject: * doc/autoconf.texi (Special Shell Variables): Mention X-Git-Tag: AUTOCONF-2.53c~18 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6eb625f2f3f41b3dcaa7359b967575238531a743;p=thirdparty%2Fautoconf.git * doc/autoconf.texi (Special Shell Variables): Mention ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD. * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL, MAILPATH and set PS1, PS2, PS4 to default values, to work around bug in pre-3.0 UWIN ksh reported by Bruce Lilly. For LC_ALL etc, first try to set to "C" as POSIX requires and as the Autoconf documentation specifies; fall back to "unset" only if this fails. Use a shell for-loop for this rather than an m4 loop, to shorten the output script. --- diff --git a/ChangeLog b/ChangeLog index 86885214b..aa3492bcd 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,16 @@ +2002-09-01 Paul Eggert + + * doc/autoconf.texi (Special Shell Variables): Mention + ENV, MAIL, MAILPATH, PS1, PS2, PS4.
