 *
 * 6-Nov-1999 JS        - see CHANGES
 * 
 * 29-Dec-1998 AdH	- Grammar and function extensions.
 *			     grammar: TOOLBAR resources, Named ICONs in 
 *				DIALOGS
 *			     functions: semantic actions for the grammar 
 *				changes, resource files can now be anywhere
 *				on the include path instead of just in the
 *				current directory
 *
 * 20-Jun-1998 BS	- Fixed a bug in load_file() where the name was not
 *			  printed out correctly.
 *
 * 17-Jun-1998 BS	- Fixed a bug in CLASS statement parsing which should
 *			  also accept a tSTRING as argument.
 *
 * 25-May-1998 BS	- Found out that I need to support language, version
 *			  and characteristics in inline resources (bitmap,
 *			  cursor, etc) but they can also be specified with
 *			  a filename. This renders my filename-scanning scheme
 *			  worthless. Need to build newline parsing to solve
 *			  this one.
 *			  It will come with version 1.1.0 (sigh).
 *
 * 19-May-1998 BS	- Started to build a builtin preprocessor
 *
 * 30-Apr-1998 BS	- Redid the stringtable parsing/handling. My previous
 *			  ideas had some serious flaws.
 *
 * 27-Apr-1998 BS	- Removed a lot of dead comments and put it in a doc
 *			  file.
 *
 * 21-Apr-1998 BS	- Added correct behavior for cursors and icons.
 *			- This file is growing too big. It is time to strip
 *			  things and put it in a support file.
 *
 * 19-Apr-1998 BS	- Tagged the stringtable resource so that only one
 *			  resource will be created. This because the table
 *			  has a different layout than other resources. The
 *			  table has to be sorted, and divided into smaller
 *			  resource entries (see comment in source).
 *
 * 17-Apr-1998 BS	- Almost all strings, including identifiers, are parsed
 *			  as string_t which include unicode strings upon
 *			  input.
 *			- Parser now emits a warning when compiling win32
 *			  extensions in win16 mode.
 *
 * 16-Apr-1998 BS	- Raw data elements are now *optionally* seperated
 *			  by commas. Read the comments in file sq2dq.l.
 *			- FIXME: there are instances in the source that rely
 *			  on the fact that int==32bit and pointers are int size.
 *			- Fixed the conflict in menuex by changing a rule
 *			  back into right recursion. See note in source.
 *			- UserType resources cannot have an expression as its
 *			  typeclass. See note in source.
 *
 * 15-Apr-1998 BS	- Changed all right recursion into left recursion to
 *			  get reduction of the parsestack.
 *			  This also helps communication between bison and flex.
 *			  Main advantage is that the Empty rule gets reduced
 *			  first, which is used to allocate/link things.
 *			  It also added a shift/reduce conflict in the menuex
 *			  handling, due to expression/option possibility,
 *			  although not serious.
 *
 * 14-Apr-1998 BS	- Redone almost the entire parser. We're not talking
 *			  about making it more efficient, but readable (for me)
 *			  and slightly easier to expand/change.
 *			  This is done primarily by using more reduce states
 *			  with many (intuitive) types for the various resource
 *			  statements.
 *			- Added expression handling for all resources where a
 *			  number is accepted (not only for win32). Also added
 *			  multiply and division (not MS compatible, but handy).
 *			  Unary minus introduced a shift/reduce conflict, but
 *			  it is not serious.
 *
 * 13-Apr-1998 BS	- Reordered a lot of things
 *			- Made the source more readable
 *			- Added Win32 resource definitions
 *			- Corrected syntax problems with an old yacc (;)
 *			- Added extra comment about grammar
