On CentOS, `make release` of Python bindings yields `include/cplxx.h:356: Error: Syntax error in input(1)`

I'm on b944eb6 and from CentOS 7.2 I'm getting the error below when I try to build the Python bindings:

[vagrant@standalone ~]$ cd prov-cpl/bindings/python
[vagrant@standalone python]$ make release
  SWIG    bindings/python/CPLDirect/cpl.i
../../../include/cplxx.h:356: Error: Syntax error in input(1).
make[2]: *** [build/release/CPLDirect.py] Error 1
make[1]: *** [all] Error 1
make: *** [release] Error 2
[vagrant@standalone python]$ cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core) 

I just made a related commit over at IQSS/dataverse@6b930af if that helps explain what I'm up to, which is to get the prov system installed as a REST service on CentOS, the preferred Linux distribution for Dataverse. Please advise. Thanks!

@jacksonokuhn figured out that the version of SWIG on CentOS 7 was too old (version 2.x). I couldn't find a SWIG 3 RPM so for now I'm manually building SWIG 3.x within the CentOS 7 Vagrant VM. I added this to the script I'm using at IQSS/dataverse@de51414
