"not enough arguments for AC_CONFIG_HEADERS" with AX_PREFIX_CONFIG_H

[Joao Luis Pinto]

Dear all:

While using the mentioned macro with autoconf 2.59 and automake 1.9.3, I 
get the above error.

configure.ac snip:

AC_INIT([My Project],[1.0.0],address@hidden,[project])
AC_CONFIG_HEADERS([config/config-h:config/config-h.in])
AC_CONFIG_SRCDIR([project/src/interface.cpp])
AC_CONFIG_AUX_DIR([config])
AC_REVISION([$Revision: 1.5 $])
AM_INIT_AUTOMAKE
AX_PREFIX_CONFIG_H([project/include/project/config.hpp],,[config/config-h])

[...]

First line of the macro reads:

AC_DEFUN([AX_PREFIX_CONFIG_H],[AC_REQUIRE([AC_CONFIG_HEADER])

Shouldn't it be AC_CONFIG_HEADERS instead?

If I make the change, the error vanishes and everything still looks OK.

Any comments/ideas?
