Yeah, it's the "or something like that" aspect of setting CFLAGS,
CPPFLAGS that I dislike.  ./configure is a black box whose inner
workings I don't know (I could find out, with a lot of work) -
I put something in and get something out but don't know how
exactly they relate.

For any flags I want to set for a lynx compilation, other than
-I and -L and -l, I now don't set them in C*FLAGS before configure,
but specify them at make time instead:

   TMPDIR=/var/tmp make SITE_DEFS="-DOK_INSTALL -DMISC_EXP" \
                        SITE_LYDEFS="-DOVERLAP"

Those always get passed down to the sub-makes as I want it (SITE_DEFS
to the ones in src and src/chrtrans, SITE_LYDEFS to the ones under
WWW/).
