+II. RedHat Linux Notes
+=======================
+
+Summary: There are known problems with the versions of libstdc++ that
+ships with both RedHat-5.1 and RedHat-5.2. You need to upgrade your
+libstdc++ before attempting to build flight gear on a RedHat system.

+my RedHat 5.2 system (brand new). After some searching I found out
+that it's got to do with a 'bug' in the stdlibc++ libraries. I picked
+up libstdc++-2.9.0-2.i386.rpm, installed it and FGFS compiled just
+fine. However, some other packages must have the libstdc++-2.8
+libraries....
+
+BTW I also solved it with the 2.8 libraries by including
+/usr/include/g++/std/bastring.cc into the example programs. I believe
+this can be done since it's a template, correct me if I'm wrong.

+III. 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. :-(

+
+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"
+ ./configure
