My email and posts are erratic this week.  Myself and 3 of my 4 kids have 
chicken pox.  Please cut me some slack as my answers may seem terse. :)

Sounds OK assuming that the newlib is the one in the rtems release directory.

If memory serves me right some of these are from rtems and some are from 
djgpp.

This rtems configuration has never been updated to djgpp v2.  You should 
only need the library binary part of the 1.12 relerase.  I should still 
have it laying around if you can't find it on the www.

The tool configuration for gcc and binutils should be exactly like it is 
in the crossgcc faq.  I can't remember what that is off the top of my 
head.  You should be able to use the one tree build procedure to get the 
linux->go32 cross.  Use that to build the rtems specific newlib.  Missing 
files and libraries should be grabbed fromt he binary library 
distribution of djgpp. 1.1[12].
