+2.3 Target Dependent Notes

+i386-go32-rtems:
+
+  1.  This is based on djgpp v1.xx.  It needs to be updated to v2.xx.
+  2.  This cannot be built one-tree style since RTEMS requires some
+      files which must be obtained from the binary distribution of the
+      djgpp library.  DJGPP can be obtained from
+      http://www.delorie.com/djgpp/dl/ofc.
+  3.  You will need to manually install a number of files from the
+      binary distribution of the DJGPP library doing something
+      like the following:
+
+      # unzip the djgpp distribution
+      cd include
+      cp dpmi.h INSTALL_POINT/lib/gcc-lib/i386-go32-rtems/2.7.2/include
+      cp go32.h INSTALL_POINT/lib/gcc-lib/i386-go32-rtems/2.7.2/include
+      cp dos.h INSTALL_POINT/lib/gcc-lib/i386-go32-rtems/2.7.2/include
+      cp pc.h INSTALL_POINT/lib/gcc-lib/i386-go32-rtems/2.7.2/include
+
+      cd ../lib
+      cp crt* INSTALL_POINT/lib/gcc-lib/i386-go32-rtems/2.7.2
+      cp libpc* INSTALL_POINT/lib/gcc-lib/i386-go32-rtems/2.7.2
+
+      # Make sure about destination on the next lines.  It keeps the newlib
+      # libc.a and the binary djgpp libc.a from conflicting.
