Did you do a full "make distclean" after you reran the configure
script?  This was caused by a left over header file, if memory serves
correctly.

If you used a separate build directory (i.e., "mkdir build ; cd build
; ../configure --enable-...") then just rm -rf the build directory and
then start from scratch.  If you used git, you can do "git clean
-xdq".  If neither of these apply, you may need to delete the full
source tree and then unpack the source tarfile again.

I'm open to patches to make this the transition between one set of
configure options to another more smooth, but given that I tend to
just do things like have multiple build directories, for things like
"build-coverity", "build-quota", "build-dietlibc", etc., it's not high
on my priority list to figure out why someone who fails to run "make
distclean", or deletes the full build tree, before running configure
with a different set of options, is losing.
