class_docstr: A simple C preprocessor that scans C source and computes, line by line,
  what the current C preprocessor #if state is.
  
  Doesn't handle everything--for example, if you have /* inside a C string,
  without a matching */ (also inside a C string), or with a */ inside a C
  string but on another line and with preprocessor macros in between...
  the parser will get lost.
  
  Anyway this implementation seems to work well enough for the CPython sources.
docstr: Returns the current preprocessor state, as a single #if condition.
