*
* Lexical analyzer for C function prototype generator
*
* This is designed to parse lexically at the top level (e.g., of extern
* objects such as procedures). The corresponding yacc-grammar expects
* that curly-braces (for function bodies) are recognized as a single
* token, BRACES. Similarly, square-brackets and their contents are
* passed back as BRACKETS.
*
* Assignments at the top level are data-initialization statements.
* These are returned as INITIALIZER.
*
* The logic here recognizes tokens inside curly-braces, but does not
* pass them back to the grammar.
*
* Apollo extensions:
* "&" is ignored when creating lint-libraries, because we ignore
* expressions of all kinds. Note that function-prototypes may use "&" to
* denote reference-parameters. By ignoring that as well, we make the
* output compatible with lint (kludge).
*
* Similarly, ignore "std_$call", since it is not compatible with lint.
*
* CPP_INLINE handles a special case of the Apollo CC 6.7 compiler that
* uses inline attribute declarations, e.g.
*
* int foo #attribute[aligned(1)];
*
* In CC 6.8 this behavior is hidden by a macro.
*
* VAX/VMS extensions:
* Treat the keywords 'globalref', etc., as 'extern'.
*
* The keywords 'noshare' and 'readonly' are type-qualifiers.
*
* GCC extensions:
* The keywords '__attribute__', '__inline', '__inline__', '__signed',
* '__signed__'.
