When configuring thusly:

#!/bin/sh

env CC=cc \
        CPPFLAGS="-I/usr/local/include -I/usr/local/src/db/db-2.4.14/Unix" \
        LDFLAGS=" -L/usr/local/lib -R/usr/local/lib
-L/usr/local/src/db/db-2.4.14/Unix" \
        ./configure \
        --disable-proctitle \
        --enable-crypt \
        --disable-bdb \
        --enable-ldbm \
        --enable-perl

#!/end

The compile of back-perl fails with errors like this:

  cd back-perl; make  all
rm -f version.c
../../../build/mkversion -v "2.2.13" back_perl > version.c

r before or at: __attribute__

This is because our perl installation was compiled with gcc.  Some of the
header
files contain __attribute__, which is a gcc extension.

For an older version of openldap, my fix was to add these lines to to
portable.h:

#if !defined(__attribute__) || !defined(__GNUC__)
#define __attribute__(A)
#endif

For this version, I also had to modify perl_back.h to place portable.h before
perl.h.
I suppose that the definition above could just be added to perl_back.h now.
