Thanks. I had read about them, but I just wrongly took for granted that 
as I was not checking AC_PROG_CC, but AC_PROG_CXX and AC_PROG_CXXCPP, it 
would work. Following your hint I did

AC_LANG_PUSH([C++])
AC_CHECK_HEADERS([iostream])
AC_LANG_POP([C++])

and it worked. But then I thought that as the whole code is supposed to 
be in C++, probably is better just to use AC_LANG

AC_PROG_CXX
AC_PROG_CXXCPP
#AC_PROG_CC
AC_PROG_RANLIB
AC_PROG_INSTALL
AC_LANG([C++])

Cheers,

Ramón.
