Please note I get the exact same errors if I try to build n compile the 
examples, as well.  Here's the 'make' line I use (in a Cygwin shell).  
This command is suggested in the README-CYGWIN.txt file in the distribution.

$ make CPPFLAGS="-Ic:/Programs/xerces-c-3.1.1/include" 
LDFLAGS="-Lc:/programs/xerces-c-3.1.1/lib"

I know it looks like I'm not specifying the Xerces library correctly, 
however, if I mistype, for example, the location of the Xerces library, 
I get the following error:


$ make CPPFLAGS="-Ic:/Programs/xerces-c-3.1.1/include" 
LDFLAGS="-Lc:/xxxxx/xerces-c-3.1.1/lib"
g++ -W -Wall -O3 -Lc:/xxxxx/xerces-c-3.1.1/lib -o driver driver.o 
hello.o -lxerces-c_3
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: 
cannot find -lxerces-c_3
collect2: ld returned 1 exit status
make: *** [driver] Error 1

Ideas?
