# [more info]:  It seems that as of XFree86 4.3.0 it is no longer
# necessary to build X with libglide3 in order to support 3dfx DRI.
# The tdfx_dri.so driver will be built either way, and appears to
# be the same.  Instead of being linked with libglide, it does
# runtime library discovery which also allows it to find versions
# of glide for all the various 3dfx cards instead of just the most
# common ones that we were including in previous builds.
#
# Just in case, we'll leave most of the glide cruft in place.

# It's VERY important to build freetype2 ourselves (or some functions are left out),

# Therefore, --prefix=/usr must be the ad-hoc standard.  Another
# rationale:  /usr is also the prefix for freetype1 (for as long as that sticks around),
# and putting them in different prefixes causes problems.  Also, we're bumping the -march
# from i386 to i486, as I can't imagine too many people are running the latest Slackware
# with X on a 386 in the year 2002.  If there are, maybe they can get away with running an
