I didn't change src/Makefile.am, so it's the same as yours. OCTINTERP_DLL_DEFS
is only applied to liboctinterp_la_CPPFLAGS, but the latter gets appended to
the compilation of oct files. Here's for instance a piece of my src/Makefile:

DLD-FUNCTIONS/liboctinterp_la-__contourc__.lo: DLD-FUNCTIONS/__contourc__.cc
#       $(LIBTOOL)  --tag=CXX $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS)
--mode=compile $(CXX) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES)
