I'm using the latest CVS version. 'xslt-config --cflags' works fine. My
problem is that the include path (/usr/include/libxml2 for me) is not passed to 
the compiler. For example, the area/Makefile.am has this include statement:
INCLUDES = \
	-DG_LOG_DOMAIN=\"libfo\" \
	$(GOBJECT_CFLAGS)	\
	-I$(top_srcdir)		\
	-I$(top_srcdir)/fo	\
	-I$(top_srcdir)/property	\
	-I$(top_srcdir)/datatype

After the automake/configure process the resulting area/Makefile has the
compile lines:
COMPILE = $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) \
	$(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS)
LTCOMPILE = $(LIBTOOL) --mode=compile $(CC) $(DEFS) $(DEFAULT_INCLUDES) \
	$(INCLUDES) $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS)

The LIBXML_CFLAGS and LIBXSLT_CFLAGS variables in the Makefile are correct
but they don't get to the compile commands.
Here is a partial output from compiling xmlroff-0.2.1:

As you can see from the error, the libxml2 include path does not get to the
compiler. If I add $(LIBXML_CFLAGS) to the INCLUDE makefile variable then
the compile works. From your email I see I should be using LIBXSLT_CFLAGS 
but the result is the same. 
Maybe I'm missing something but I don't see it.
