I did some more searching also and have had moderate success.  I
downloaded, built and installed ioperm for cygwin.  Then added it to
the list of libraries to be linked.  Then found, downloaded, and added
getline.c to the cmdline directory build.  Then commented out the code
to call write_history() in the JTAGERs exit function.  It now sort of
works.  I can attach to my ARM7TDMI processor, set registers, etc.  I
hacked some code to kind-of support my flash part and have been able
to erase and attempt to program it.  The program once loaded into
flash almost works.  Not sure if I have a programing problem or a
program problem - flash access time.  Unfortunately JTAGER does not
support Thumb mode which is what my loaded program executes, so I have
been unable to erase and retry.
BTW - programing flash with JTAGER is VERY, VERY slow.  It would be
better to use JTAGER (or something) to load a program into RAM then
use it to program the flash.

Sorry,

I was downloading and compiling various things under both Linux and
Cygwin. I thought I compiled JTAGER under cygwinas well as Linux, but I did not.

ioperm is available for cygwin - just install the package and explicitly link with
the ioperm library. 

Having now actually tried to compile JTAGER under cygwin, it seems that it needs
a function called "getline" which is avialable in glibc. It looks to be fairly easy to 
implement this missing function. Everything else seems to be available.
