BUG #5283: Missing "base/1/ON" file during initdb

The following bug has been logged online:

Bug reference:      5283
Logged by:          Robert Treat
Email address:      xzilla@users.sourceforge.net
PostgreSQL version: 8.4.2
Operating system:   Slackware Linux 2.6.23.14-grsec
Description:        Missing  "base/1/ON" file during initdb
Details:

Trying to install 8.4.2 on Linux 2.6.23.14-grsec from source tarball

configure line is this:

./configure '--prefix=/usr/local/pgsql-8.4.2' '--enable-debug'
'--enable-depend' '--enable-cassert' '--enable-thread-safety'
'--with-libxml' '--disable-largefile'

I added --disable-largefile to configure after getting the following error
during "make install"

access/transam/xlog.o: In function `XLogFileClose':
/usr/local/src/postgresql-8.4.2/src/backend/access/transam/xlog.c:2610:
undefined reference to `posix_fadvise64'
storage/file/fd.o: In function `FilePrefetch':
/usr/local/src/postgresql-8.4.2/src/backend/storage/file/fd.c:1096:
undefined reference to `posix_fadvise64'
collect2: ld returned 1 exit status
make[2]: *** [postgres] Error 1

With largefile support disabled, make install worked fine, but now I am
getting the following error during initdb.

root@phppgadmin:/usr/local/src/postgresql-8.4.2/src# sudo -u postgres
/usr/local/pgsql-8.4.2/bin/initdb -D /usr/local/pgsql/data/84/

I've installed 7.old -> 8.3 on this machine before, so this seems like
something new in 8.4. Any help is appreciated.
