According to the value in the Makefile, this:

if EVIL_HAVE_WINCE

libevil_la_LINK = $(LINK) $(libevil_la_CFLAGS) $(libevil_la_LDFLAGS)

else

libevil_la_CXXFLAGS = -fno-rtti -fno-exceptions
libevil_la_LINK = $(CXXLINK) $(libevil_la_CXXFLAGS) $(libevil_la_LDFLAGS)

endif


is sufficient. The *_C(XX)FLAGS can even be removed. Technically, its 
value should not contain linker flags.

thank you
