There's nothing in Makefile.am that makes use of the substitution 
variables, so configure doesn't actually emit code to define the 
matching preprocessor macros.

I tried to change that, by putting "DEFS = @DEFS@" into 
libvtv/Makefile.am (libvtv/Makefile.in is derived from that).  The diff 
below is slightly garbled, but you get the idea.

diff --git a/libvtv/Makefile.am b/libvtv/Makefile.am

  AM_CPPFLAGS = -I$(top_srcdir)/../include
  AM_CFLAGS = $(XCFLAGS)
  AM_CCASFLAGS = $(XCFLAGS)


But I ended up with:

(The caret is at the wrong position, IMHO.)

But I suspect something went wrong with regenerating Makefile.in.  Have 
you got automake 1.11?  Then you could make the change, regenerate 
Makefile.in, and try again.
