! 78: * The variable 'mcpp_mode' specifies the mode of preprocessing as one of
! 79: * OLD_PREP, KR, STD, or POST_STD.
! 80: * Those modes have many differences each other --
! 81: * i.e. handling of translation phases; handling of some
! 82: * preprocessing tokens; availability of some directives; way of
! 83: * macro expansion;
! 84: * -- as follows.
! 85: *
! 86: * KR Actual arguments of a macro are expanded (after substitution)
! 87: * with rest of the replacement text and the subsequent source text.
! 88: * ## in macro definition has no significance to cpp. The surrounding
! 89: * tokens are macro-expanded separately. Also, # has no significance
! 90: * to cpp. The following token is expanded.
! 91: * Directly or intermediately recursive macro call causes an error.
! 92: * <backslash><newline> sequence is deleted only in string literals
! 93: * and in #define directive lines.
! 94: * sizeof (type) can be used in #if line.
! 95: * KR corresponds to the "K&R 1st."
! 96: *
! 97: * OLD_PREP In addition to the KR specifications, this mode has the
! 98: * following characteristics (and some others).
! 99: * Converts comment to 0 space instead of 1 space.
! 100: * Expands the parameter like spelling in string literal as a macro.
! 101: * Does not check unmatched pair of '"' or '\''.
! 102: * OLD_PREP corresponts to "Reiser model" cpp.
! 103: *
! 104: * STD Standard conforming mode.
! 105: * <backslash><newline> sequence is always deleted after trigraph
! 106: * conversion and before tokenization.
! 107: * Digraph sequences are recognized as tokens.
! 108: * Actual arguments of a macro are expanded separately prior to
! 109: * re-scanning of the replacement text.
! 110: * The name in the replacement text once expanded is not re-expanded,
! 111: * thus preventing recursive death.
! 112: * ## in macro definition concatenates tokens. The tokens are not
! 113: * expanded. The concatenated token is expanded by rescanning.
! 114: * # in macro definition stringizes the following argument. The argument
! 115: * is not expanded. \ is inserted before " and \ in or surrounding
! 116: * the string literal or character constant.
! 117: * An expanded macro is surrounded by spaces to prevent unintended
! 118: * token merging.
! 119: *
! 120: * POST_STD This mode simplifies the behavior of STD mode as follows.
! 121: * 1. Digraph sequences are converted in translation phase 1, as
! 122: * alternate characters rather than as tokens.
! 123: * 2. A space is inserted as a token separator between any tokens in
! 124: * a source (except a macro name and the next '(' in macro
! 125: * definition): thus simplifying tokenization, test of macro
! 126: * redefinition and macro expansion, especially "stringization".
! 127: * 3. Test of macro redefinition ignores difference of parameter names,
! 128: * test of which has little utility and not a little overhead.
! 129: * 4. #if expression forbids character constants, which have little
! 130: * portability, little utility and not a little overhead.
! 131: * 5. Rescanning of a macro expansion is limited in the replacement
! 132: * text, rest of the source file is not scanned, thus making the
! 133: * syntax of "function-like" macro call more similar to that of
! 134: * function call.
! 135: * 6. Argument of #include directive in <header.h> form is an obsolescent
! 136: * feature.
! 137: * 7. '$' or so are not treated specially in #define directive.
! 138: * 8. Trigraphs, UCN (universal-character name) are not recognized.
! 139: * 9. Multi-byte characters in an identifier are not recognized.
! 140: *
! 141: * The following specifications are available when mode is STD or POST_STD.
! 142: * preprocessing number token, digraphs,
! 143: * #pragma (#pragma MCPP put_defines, #pragma MCPP warning
! 144: * , #pragma MCPP debug) directive,

! 150: * _Pragma() operator, variable-arguments macro,
! 151: * macro as an argument of #include, #line directives,
! 152: * escape sequences \x[hex-digits], \a, \v,
! 153: * '+' option (C++ preprocessing),
! 154: * 'S<n>' option (re-defines __STDC__ as <n>, unpredefine some macros),
! 155: * 'V<n>' option (re-defines __STDC_VERSION__ or __cplusplus as <n>),
! 156: * 'h<n>' option (re-defines __STDC_HOSTED__ as <n>).
! 157: * The following specifications are available only in STD mode.
! 158: * Trigraphs and UCN,
! 159: * Multi-byte characters in an identifier.
! 160: * The following specifications are available only in KR and OLD_PREP modes.
