#pragma prototyped
/*
* Glenn Fowler

*
* preprocessor data
*
* intended to be a conforming implementation of the translation phases
* (2.1.1.2) 1,2,3,4 and 6 of the "American National Standard for
* Information Systems -- Programming Language -- C", ANSI X3.159-1989.
*
* STANDARD INTERPRETATION:
*
* include files are forced to preserve #if nesting levels
* support for this is found in the recursive description for
* include file processing in the translation phases
*
* ID"..." produces two tokens: {ID}{"..."}
* ID'...' produces two tokens: {ID}{'...'}
*
* COMPATIBILITY:
*
* only sane Reiser compatibility is implemented
*
* strange handling of `\newline', especially in directives,
* is not implemented
*
* dissappearing comments used as concatenation operators work
* only within macro bodies
