-Native SGI Irix Compilers
-=========================
+IV. Procedure to build FGFS with Native SGI Irix Compilers from CVS Sources
+===========================================================================
+
+(Contributed by Todd Smith <msmith@sikorsky.com>)
+
+Download the latest version of plib (1.0.3) from:
+
+    http://www.woodsoup.org/~sbaker/plib/
+
+Install it both in /usr/local/plib and /usr/local/include/plib.  I
+think that I am using it from /usr/local/include.
+
+Download the FlightGear-0.6 via anonymous cvs as usual, then do:
+
+> aclocal		# normal
+> automake -a -i	# added '-i' flag to avoid dependency calc
+			# that only sgi cc/CC doesn't support
+> autoconf		# normal
+
+Note the change in automake's command argument.
+
+Now set env variables to use native compilers (csh syntax).
+
+> setenv CC cc
+> setenv CXX CC
+> setenv CFLAGS '-Xcpluscomm -DEBUG:suppress=1001,1012,1014,
+                            1116,1172,1174,1401,1460,1551,1552'
+> setenv CXXFLAGS '-DEBUG:suppress=1001,1012,1014,1116,1172,
+                          1174,1401,1460,1551,1552,3303,3322'
+
+The '-DEBUG:suppress=' stuff just suppresses anonying warnings during
+compile.  The meaning of each one is shown later in this file.
+You can use all or none of these here.
+
+> setenv CPPFLAGS '-woff 1014'
+
+This is required so that configure will really believe that plib
+is installed.  ( Otherwise a compiler warning makes configure
+that plib/pu.h couldn't be found. )
+
+> ./configure
+> find . -name Makefile -exec irix-hack.pl {} \;	# normal irix hack
+> gmake
+
+Runs great.

+V. Additional Native SGI Irix Compilers Notes
+=============================================
 
 If you are building with native SGI compilers try running configure like the
 following (assuming sh syntax):
 
-  CC=cc CXX=CC CFLAGS=-Xcpluscomm ./configure
+  CC=cc CXX=CC CFLAGS="-Xcpluscomm -woff 1014" ./configure
 
 Then (and this step is *VERY* important for your success) run the following 
 command:

 under construction stuff right now (3/9/99) and if you get that far, 
 rejoice because it means the simulator was successfully built in the 
 Simulator/Main subdirectory.
+
+Special note for those Irix users using the native compilers *AND* checking
+out the current source tree via CVS:
+
+You will need to run "aclocal ; automake -a ; autoconf" as per 
+README.autoconf, but you need an additional flag for automake to disable
+automatic dependency building (which breaks the native Irix compilers.)
+You should instead run:
+
+    aclocal ; automake -a --include-deps; autoconf
+
+Then, proceed on to the configure step.
