Subject: [PATCH] configure*: Fix wrong quote character in AC_MSG_ERROR
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Square brackets are used as quotes in autoconf.

From Section 8.1.1, Active Characters of the Autoconf manual[1]:

> To fully understand where proper quotation is important, you first
> need to know what the special characters are in Autoconf: ‘#’
> introduces a comment inside which no macro expansion is performed, ‘,’
> separates arguments, ‘[’ and ‘]’ are the quotes themselves, ‘(’ and
> ‘)’ (which M4 tries to match by pairs), and finally ‘$’ inside a macro
> definition.
