Mark,

I have attached a log of the configure session with set -xv.  Don't
worry, it bombs out early, so it isn't that big.  I'll do the same
procedure on win2k, if you want.  The offending checkpoint is:

  -enable-* | --enable-*)
    ac_feature=`expr "x$ac_option" : 'x-*enable-\([^=]*\)'`
    # Reject names that are not valid shell variable names.
    expr "x$ac_feature" : ".*[^-_$as_cr_alnum]" >/dev/null &&
      { echo "$as_me: error: invalid feature name: $ac_feature" >&2
   { (exit 1); exit 1; }; }   
    ac_feature=`echo $ac_feature | sed 's/-/_/g'`
    case $ac_option in
      *=*) ac_optarg=`echo "$ac_optarg" | sed "s/'/'\\\\\\\\''/g"`;;
      *) ac_optarg=yes ;;
    esac
    eval "enable_$ac_feature='$ac_optarg'" ;;

The options I'm passing are:

CFLAGS=-O2 \
LDFLAGS= \
CC=gcc-2 \
CXX=g++-2 \
../dist/configure --target=i686-pc-cygwin --prefix=/usr
--exec-prefix=/usr --sysconfdir=/etc --bindir=/usr/bin
--libdir=/usr/lib --includedir=/usr/include/db3.1
--datadir=/usr/share '--libexecdir=${sbindir}' --localstatedir=/var
'--program-transform-name=s,^db_,db3.1_,' --enable-posixmutexes
--enable-dynamic --enable-cxx --enable-compat185 --disable-test

If you (or anyone else) are interested in seeing what it does on your
system, you can grab the self-contained build system at:

http://today.clemson.edu/temp/db-3.1.17-1-src.tar.bz2

Untar to a temporary dir and run the buildscript like so:
./db-3.1.17-1.sh prep

Then edit the configure script [db-3.1.17/dist/configure] adding your
-xv flags to line 1 and line 155 [exec "$CONFIG_SHELL" "-xv"]:

Then run:
./db-3.1.17-1.sh conf

It should run fine on win2k, but winme/9x it doesn't.  I'm going to
try and examine it some more, but I thought I'd bring you in on it.

Cheers,
Nicholas
