Basically you will have to change acinclude.m4 to test for cygwin, and 
set the various build variables (SOSUFFIX, JMODSUFFIX, etc). Because 
cygwin DSOs don't have the "lib" prefix, you might have to do something 
for prefix as well as suffix.

I separated the various parts of acinclude.m4 out into different files 
in the aclocal directory, so modify them (sosuffix.ac) there and then 
do

  cat aclocal/*.ac >acinclude.m4

to make the final acinclude file.

If you add prefix-handling code, you need to modify Makefile.am to get 
it to be reflected in the build: grep for JMODSUFFIX for the lines that 
need to be changed. Afterwards you need to do aclocal, automake etc 
before reconfiguring.

GNU JAXP includes both a 100% Java parser (Ælfred and the GNU DOM 
implementation) and the libxmlj parser which uses libxml2. The two 
serve different purposes: Ælfred + GNU DOM is easier to deploy, while 
libxmlj is very fast and has support for additional features such as 
XPath and XSLT transformations.

There should probably be a configuration option not to build one or 
other of these; again, build system patches would be greatly 
appreciated!
