+II.  Linux/AXP Notes
+====================
 
+As of 2/19/99 I'm not aware of any glide port to Linux/AXP so it's
+software rendering only for now.  :-(
 
+This following information is contributed by "Daniel J. Frasnelli"
+<dfrasnel@csee.wvu.edu>
+
+1) Mesa was not built correctly by default.  I had to add the "-mieee"
+flag to the Make-config for Mesa-3.1beta1 to fix the problem.  After
+building and installation, all of the problems I had previously with
+GL programs under AlphaLinux disappeared.
+
+2) I also had to set the '-mieee' flag in $CFLAGS before configuring
+and building FGFS.  The -mieee switch fixes floating point exception
+handling.
+
+I heavily optimized both Mesa and FGFS, using the libffm "fast math
+library for Alpha" in preference over the default libm, sticking all
+sorts of strange flags in $CFLAGS, etc.  These flags should be
+adjusted for your specific architecture:
+
+    export CFLAGS="-mieee -mcpu=ev56 -Wa,-m21164a -pipe -g"
+    export CXXFLAGS="-mieee -mcpu=ev56 -Wa,-m21164a -pipe -g"
