+#  Make header for PgP SSX builds
+#
+# The application may define the following variables to control the
+# build process:
+#
+# IMG_INCLUDES       : Aplication-specific header search paths
+#
+# DEFS               : A string of -D<symbol>[=<value>] to control compilation
+#
+# SSX_SRCDIR         : Default ..; The path to the SSX source code.
+#                      The default is set for building the SSX
+#                      subdirectories. 
+#
+# SSX_THREAD_SUPPORT : (0/1, default 1); Compile SSX thread and
+#                      semaphore suppprt 
+#
+# SSX_TIMER_SUPPORT  : (0/1, default 1); Compile SSX timer suppprt
+#
+# PPC405_MMU_SUPPORT : (0/1, default 1); Compile for PPC405 simple MMU protection
+#
+# SIMICS_ENVIRONMENT : (0/1, current default 0); Compile for Simics
+#
+# SIMICS_MAGIC_PANIC : (0/1, current default 0); Use Simics Magic
+#                      breakpoint for SSX_PANIC() instead of PowerPC trap.
+#                      Note that Simics does not model trap correctly in
+#                      external debug mode.
+#
+# GCC-O-LEVEL        : The optimization level passed to GCC (default -Os). May
+#                      also be defined empty (GCC-O-LEVEL=) to disable
+#                      optimization. This variable can also be used to pass
+#                      any other non-default setting to GCC, e.g.
+#                      make GCC-O-LEVEL="-Os -fno-branch-count-reg"
+#
+# GCC-TOOL-PREFIX    : The full path (including executable file prefixes) to
+#                      the GCC cross-development tools to use.  The default is 
+#                      "ppcnf-mcp5-"
+#
+# CTEPATH            : This variable defaults to the afs/awd CTE tool
+#                      installation - The PORE binutils are stored there. If
+#                      you are not in Austin be sure to define CTEPATH in
+#                      your .profile.
