61    - AC_DEFINE/AC_DEFINE_UNQUOTED
62    
63      We have to stop using the old compatibility scheme --that tried to
64      avoid useless backslashes-- because Libtool 1.4.3 contains a
65    
66      AC_DEFINE([error_t], [int],
67                [Define to a type to use for \`error_t' if it is not
68                 otherwise available.])
69    
70      We have to quote the single quotes and backslashes with \.  The old
71      compatibility scheme saw that ` was backslashed, and therefore did
72      not quote the single quote...  Failure.  Hence, Autoconf 2.54 is not
73      compatible with Libtool.  Autoconf 2.55 is, but in some cases might
74      produce more \ than wanted.
75    
76      Please, note that in the future the same problem will happen with
77      AC_MSG_*: use `autoreconf -f -Wall'.

122    - AC_MSG_*
123    
124      Special characters in AC_MSG_* need not be quoted.  Currently,
125      Autoconf has heuristics to decide when a string is escaped, or has
126      to be escaped.  This scheme is fragile, and will be removed; the
127      only risk is uglified messages.  Please, run `autoreconf -f -Wall'
128      to find occurrences that will be affected.
