./autogen.sh fails on error: automatic de-ANSI-fication support has been removed

[spyysalo]

On Ubuntu 13.10, after downloading and unpacking crfsuite master:

./autogen.sh
...
aclocal: warning: autoconf input should be named 'configure.ac', not 'configure.in'
configure.in:33: error: automatic de-ANSI-fication support has been removed
/usr/share/aclocal-1.13/obsolete.m4:26: AM_C_PROTOTYPES is expanded from...
configure.in:33: the top level
autom4te: /usr/bin/m4 failed with exit status: 1
aclocal: error: echo failed with exit status: 1
aclocal failed!

removing the offending macro by replacing

AM_C_PROTOTYPES

with

dnl AM_C_PROTOTYPES

in configure.in fixes the (immediate) issue.

[pscholl]

this can also be solved by replacing the deprecated macro:

diff --git a/configure.in b/configure.in
index dafbcf6..b5838bb 100644
--- a/configure.in
+++ b/configure.in

This has also been fixed in the unmerged pull-request #29.
