+# The following options allow particular compatibility modes to be
+# enabled, when they require specialised support from the startup
+# process. These can affect the environment in which the program
+# runs.
+#
+# CYGSEM_START_ISO_C_COMPATIBILITY enables compatibility with ISO C,
+# in particular in eCos it creates a thread that invokes the function
+# main() which the user must supply. It does this by invoking the function
+# cyg_iso_c_start(). For more information, refer to the C library
+# documentation.
+#
+# CYGSEM_START_UITRON_COMPATIBILITY enables compatibility with uItron.
+# You must configure uItron with the correct tasks, and then enabling this
+# option starts the uItron subsystem. It does this by invoking the function
+# cyg_uitron_start().
+#
+# Both these can also be done by the user overriding cyg_user_start(),
+# cyg_package_start(), or cyg_prestart(). Refer to the documentation on
+# how and when to do this.

+        (libc) within the system version of cyg_package_start().
+        This enables compatibility with ISO C, in particular in
+        eCos it creates a thread that invokes the function main()
+        which the user must supply.
+        It does this by invoking the function cyg_iso_c_start().
+        If this is disabled, and you want to use the C library, you
