# We may be splitting this out at a later date.  Also, it seems prudent to move this into
# /usr rather than /usr/X11R6, as *many* source bits won't find ft2build.h in /usr/X11R6/include
# without some patching.  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
# earlier version of X.  :-)

# wasted many hours here always leading to a failed build or no libXft.  It's best to let
# X just do it's own thing and then fix the problems with freetype2 after the build.
