autoconf and epel-5

[Simon Wesp <cassmodiah fedoraproject org>]

Hi all,

i have a little issue with autoconf and epel-5

the statement of the problem:

in configure.ac stands: 
CXXFLAGS="-Wall -O2"

to honor the rpmoptflags i removed this line and create a patch of my
changes.

now i have to run autoconf to implement my changes. no problem in
fedora. in epel-5 it will abort:
http://buildsys.fedoraproject.org/logs/fedora-5-epel/1476-hosts3d-0.97-3.el5/i386/build.log



my idea to handle this problem is:

1) run autoconf in fedora and create a diff of the changes (as patch1)

2) handle it in the specfile: 

%if 0%{?fedora}
BuildRequires:   autoconf
%endif

%prep
%setup -q -n %{name}-%{srcversion}

# Patch to remove CXXFLAGS from configure.ac
%patch0 -p1 

%if 0%{?rhel}
# Patch for autoconf 2.60
%patch1 -p1
%endif


%build
%if 0%{?fedora}
autoconf
%endif


is this the right way to solve this problem? i didn't found a helpful
text passage in the packaging-guidelines
