I looked at specctra_lexer.h (attached) and sure enough it has an unbalanced
#ifndef / #endif. This file is apparently auto-generated by cmake - I have no

* DSNLEXER in the same compilation unit, say by mutliple header file inclusion.
* Plus this also enables re-use of the same enum name T. A typedef can always be used
* to clarify which enum T is in play should that ever be a problem. This is
