Marc G. Fournier d077c61492 From: Michael Meskes <Michael_Meskes@topmail.de> 
+
+ Tue Feb 23 17:32:25 CET 1999
+
+       - Other than a struct a union itself cannot be specified as variable.
+
+ Fri Feb 26 07:18:25 CET 1999
+
+       - Synced preproc.y with gram.y.
+
+ Sat Feb 27 20:30:03 CET 1999
+
+       - Added automatic allocating for NULL pointers.

/* OK, here is a short description of lex/flex rules behavior.
* The longest pattern which matches an input string is always chosen.
* For equal-length patterns, the first occurring in the rules list is chosen.
* INITIAL is the starting condition, to which all non-conditional rules apply.
* When in an exclusive condition, only those rules defined for that condition apply.
*
* Exclusive states change parsing rules while the state is active.
* There are exclusive states for quoted strings, extended comments,
* and to eliminate parsing troubles for numeric strings.
* Exclusive states:
* <xb> binary numeric string - thomas 1997-11-16
* <xc> extended C-style comments - tgl 1997-07-12
* <xd> delimited identifiers (double-quoted identifiers) - tgl 1997-10-27
* <xh> hexadecimal numeric string - thomas 1997-11-16
* <xm> numeric strings with embedded minus sign - tgl 1997-09-05
* <xq> quoted strings - tgl 1997-07-30
*
* The "extended comment" syntax closely resembles allowable operator syntax.
* So, when in condition <xc>, only strings which would terminate the
* "extended comment" trigger any action other than "ignore".
* Be sure to match _any_ candidate comment, including those with appended
* operator-like symbols. - thomas 1997-07-14
