Hmpd. I am not exactly sure why you advocate supporting .c or .f, .f90, .f95,
.m and .mm none of which are likely to work _in any way_ with the parsing
done and scaffolding added by sourceCpp.  When you read 'sourceCpp', mentally
stress the last three letters.

This is for R and C++.  And the file extension is .cpp (with a bit of luck
you may get .cc).  

The rest is user error.  You can't try and catch everything.
