Ehm, no.  How embarassing: I kept looking at the compilation log (seeing the the
-rpath option was passed to libtool) without checking again with rpmlint -i. 
Thanks!

Sorry, I don't understand.  Where did you take "CXXFLAGS="$RPM_OPT_FLAGS"
./configure ..."?  Are you saying that in the spec file I should replace

%build
%configure --enable-shared --disable-rpath
make

with

%build
CXXFLAGS="$RPM_OPT_FLAGS" ./configure --enable-shared --disable-rpath
make

?

In configure.ac there is the following:

# If we are using GCC we want to compile with warnings enabled.
if test x"$GCC" = xyes
then
  CFLAGS="-W -Wall $CFLAGS"
fi
if test x"$GXX" = xyes
then
  CXXFLAGS="-W -Wall $CXXFLAGS"
fi

Plus the following code implementing the --enable-optimization configure option.

arch=no
enableval=standard
AC_MSG_CHECKING([whether to enable optimizations])
AC_ARG_ENABLE(optimization,
  AC_HELP_STRING([--enable-optimization],
    [enable compiler optimizations]))
case "${enableval}" in
sspeed)
  AC_MSG_RESULT(sspeed)
  OPT_FLAGS="$OPT_FLAGS -O3 -fomit-frame-pointer"
  arch=yes
  ;;
speed)
  AC_MSG_RESULT(speed)
  OPT_FLAGS="$OPT_FLAGS -O3"
  arch=yes
  ;;
size)
  AC_MSG_RESULT(size)
  OPT_FLAGS="$OPT_FLAGS -Os"
  arch=yes
  ;;
standard | yes)
  AC_MSG_RESULT(standard)
  OPT_FLAGS="$OPT_FLAGS -O2"
  ;;
mild)
  AC_MSG_RESULT(mild)
  OPT_FLAGS="$OPT_FLAGS -O1"
  ;;
zero)
  AC_MSG_RESULT(zero)
  OPT_FLAGS="$OPT_FLAGS -O0"
  ;;
no)
  AC_MSG_RESULT(no)
  ;;
*)
  AC_MSG_ERROR([bad value ${enableval} for --enable-optimization, needs sspeed,
speed, size, standard, mild, zero, yes or no])
  ;;
esac

>From what you write I gather this is not good.  What can we do to improve the
situation?
