+ * Description:
+ *   This function is called by the OS when one or more
+ *   signal handling actions have been queued for execution.
+ *   The architecture specific code must configure things so
+ *   that the 'igdeliver' callback is executed on the thread
+ *   specified by 'tcb' as soon as possible.
+ *
+ *   This function may be called from interrupt handling logic.
+ *
+ *   This operation should not cause the task to be unblocked
+ *   nor should it cause any immediate execution of sigdeliver.
+ *   Typically, a few cases need to be considered:
+ *
+ *   (1) This function may be called from an interrupt handler
+ *       During interrupt processing, all xcptcontext structures
+ *       should be valid for all tasks.  That structure should
+ *       be modified to invoke sigdeliver() either on return
+ *       from (this) interrupt or on some subsequent context
+ *       switch to the recipient task.
+ *   (2) If not in an interrupt handler and the tcb is NOT
+ *       the currently executing task, then again just modify
+ *       the saved xcptcontext structure for the recipient
+ *       task so it will invoke sigdeliver when that task is
+ *       later resumed.
+ *   (3) If not in an interrupt handler and the tcb IS the
+ *       currently executing task -- just call the signal
+ *       handler now.

+ZDS-II Compiler Versions
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+4.11.0
+  This is the only version that this code has been built against.
+  
+  Although it compiles without error, the 4.11.0 compiler generates
+  bad code on one of the files, mm/mm_initialize.c.  Below is a simple work-
+  around.

+
+Other Versions
+  If you use any version of ZDS-II other than 4.11.0 or if you install ZDS-II
+  at any location other than the default location, you will have to modify
+  two files:  (1) configs/ez80f910200kitg/*/setenv.sh and (2)
+  configs/ez80f910200kitg/*/Make.defs.
+
+Configuration Subdirectories
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- src/ and include/
+    These directories contain common logic for all ez80f910200kitg
+    configurations.
+
+Variations on the basic ez80f910200kitg configuration are maintained
+in subdirectories.  To configure any specific configuration, do the
+following steps:
+
+   cd <nuttx-top-directory>/tools
+   ./configure.sh ez80f910200kitg/<sub-directory>
+   cd <nuttx-top-directgory>
+   make
+
+Where <sub-directory> is the specific board configuration that you
+wish to build.  The following board-specific configurations are
+available:
+
+- ostest
+    This builds the examples/ostest application for execution from FLASH.
+    See examples/README.txt for information about ostest.

+Check out any README.txt files in these <sub-directory>s.

+This is the output from the z16f target from January 31, 2008

+4.10.1
+  The ZDS-II version 4.10.2 will not compile NuttX.  It reports "internal
+  errors" on one of the files, mm/mm_initialize.c.  Below is a simple work-

+4.9.5
+  This is the latest tool version listed on the ZiLOG site for the Z8F6403.

+
+Other Versions
+  If you use any version of ZDS-II other than 4.10.1 or if you install ZDS-II
+  at any location other than the default location, you will have to modify
+  two files:  (1) configs/z8f64200100kit/*/setenv.sh and (2)
+  configs/z8f64200100kit/*/Make.defs.
+
+Configuration Subdirectories
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- src/ and include/
+    These directories contain common logic for all z8f64200100kit
+    configurations.
+
+Variations on the basic z8f64200100kit configuration are maintained
+in subdirectories.  To configure any specific configuration, do the
+following steps:
+
+   cd <nuttx-top-directory>/tools
+   ./configure.sh z8f64200100kit/<sub-directory>
+   cd <nuttx-top-directgory>
+   make
+
+Where <sub-directory> is the specific board configuration that you
+wish to build.  The following board-specific configurations are
+available:
+
+- ostest
+    This builds the examples/ostest application for execution from FLASH.
+    See examples/README.txt for information about ostest.
+
+Check out any README.txt files in these <sub-directory>s.
