[CWB] rcqp installation / compilation

[Andreas Blätte]

Dear colleagues,

if I recall it correctly, the problem occurs with rcqp version 0.5 that 
you get via svn. The version 0.4 available at CRAN 
(https://cran.r-project.org/package=rcqp) is stable.

For the R package polmineR I am working on, I've experimented with Rcpp 
wrappers to expose CWB/CL functionality in R (see 
https://github.com/PolMine/polmineR.Rcpp). It works fine for my 
purposes, but it is not yet documented properly and does not do all the 
safety checks that make the rcqp stable and reliable.

Kind regards

Andreas
