[Gm2] latest cvs checkins

[Gaius Mulley]

Hi,

here are the latest checkins.  Of note is that the compiler now is 15%
faster for large files (possibly better than that for small source
files).  gm2/gm2-compiler/SymbolTable.mod now uses dynamic data
structures.  It uncovered a few uninitialised fields (which the
underlying operating system would have memset(.., 0, ...) the complete
array upon execution.  All regression tests pass with these changes
on the x86_64

   * All major arrays are now dynamic within gm2.
   * gm2/gm2-libs/FIO.mod:  corrected spelling mistake.
   * gm2/gm2-compiler/SymbolTable.mod:  large number of changes
     replacing static arrays, Symbol, and ScopeCallFrame
     with Indexing.Index dynamic arrays.  Also fixed a number
     of uninitialized fields in the symbol table.
   * gm2/tools-src/array2index.py:  tool used to replace the
     static arrays with their dynamic equivalent.
   * gm2/gm2-compiler/SymbolTable.mod:  fixed another
     uninitialised Scope field in MakeHiddenType.

I've also rebuilt the i686 debian package (with its original contents
as the package builder configuration was incorrect).

regards,
Gaius
