failure building static 0.15.9

[Allyn Fratkin]

hi bogofilter-dev guys.

i'm having a problem compiling bogofilter 0.15.9 statically
on redhat 9.  i always build static versions of bogofilter for use on
my web host's system where my mail is delivered.  this hasn't
been a problem before (last version i built was 0.14.5.4).
but 0.15.9 is eluding me.

first problem to note is that there has always been an issue with
redhat (8 and 9) that i don't understand: a libdb.so is shipped
but not a libdb.a .  so i've always specifically had to modify the
Makefile to indicate -ldb-4.0 so the linker can find the archive
version of the db lib.

now there's a new --enable-static version of configure.  this problem
isn't fixed like i thought it would be.  so i've finally modified my
system to make a symlink from libdb.a pointing to libdb-4.0.a .
(but i still think this is a bug in configure).

unfortunately the compile still fails with the following errors:
