Build of 0.6.2 fails

[Michael Ströder <michael@stroeder.com>]

HI!

I'm trying to build heimdal 0.6.2 on my SuSE 9.0 system with the following 
build script:

---------------------------------- snip ----------------------------------
BDB="/usr/local/Berkeley-DB-4.2"

export CFLAGS="-O4 -march=pentium4 -mcpu=pentium4"
export CPPFLAGS="-I$BDB/include"
export LDFLAGS="-L$BDB/lib "
export LD_LIBRARY_PATH="$BDB/lib"

./configure \
   --prefix=/opt/heimdal \
   --with-krb4=no \
   --enable-shared=yes \
   --enable-static=yes \
   --enable-osfc2 \
   --with-openldap=/usr/local/openldap-OPENLDAP_REL_ENG_2_2 \
   --with-x
make
---------------------------------- snip ----------------------------------

But it fails with

---------------------------------- snip ----------------------------------
gcc  -DHAVE_CONFIG_H -I. -I. -I../../include -I../../include 
-I../../lib/roken -I../../lib/roken   -I/usr/include/et

-Wpointer-arith -Wbad-function-cast -Wmissing-decla
rations -Wnested-externs -O4 -march=pentium4 -mcpu=pentium4 -c `test -f 
'conf.c' || echo './'`conf.c

What is missing on my system?
