autogen.sh fails on autoconf 2.69c

[trofi]

It's a forward of downstream https://bugs.gentoo.org/750728 where cronie fails on autoconf-2.69c (soon to be autoconf-2.70).

$ ./autogen.sh
/usr/bin/m4:configure.ac:1: Warning: excess arguments to builtin `m4_define' ignored
autom4te-2.70_beta2: error: /usr/bin/m4 failed with exit status: 1
aclocal-1.16: error: echo failed with exit status: 1
autogen.sh: exit on error

It happens because autoconf-2.70 slightly changed quotation around AC_INIT and fails more prominently if there is not just an email address. The following workaround seems to fix it:

--- a/configure.ac
+++ b/configure.ac
@@ -1,4 +1,4 @@
-AC_INIT([cronie],[1.5.5],[[email protected],[email protected]])
+AC_INIT([cronie],[1.5.5],[[email protected]])
 AC_CONFIG_HEADER([config.h])
 AC_PREREQ(2.60)

Fixed, dropping the e-mail altogether. Thank you for the report.
