Using gnuwin and xsltproc in Windows 8.1

My attempt to use xsltproc from gnuwin in Windows 8.1 is met with 
failure because of missing imports in libxml2 of gnuwin. The actual 
message I am seeing when I attempt to run "xsltproc -version" is:

"The procedure entry point xmlDefaultSAXHandler could not be located in 
the dynamic link library C:\Utilities\GnuWin\bin\xsltproc.exe."

If I look at Dependency Walker it shows that libxml2.dll has a number of 
unresolved imports including xmlDefaultSAXHandler, xmlIndentTreeOutput, 
xmlLoadExtDtdDefaultValue, and xmlParserVersion.

Is gnuwin unusable under Windows 8.1 ? If not, what do I need to do to 
get it to work properly ?
