## $(SHLIB) is the usual default target that is built automatically from all source 
## files in this directory. userLibrary is an additional target for the second library
## that will be installed in ../inst/lib$(R_ARCH) and which users can link against.

## C++0x enabled if 
## - the environment variable RCPP_CXX0X is set to yes
## - it makes sense (GCC >= 4.3)
ifeq ($(RCPP_CXX0X),yes)
