	* gm2/gm2-gcc/m2builtins.c:  removed trailing spaces.  define_builtin
          (New procedure).  m2builtins_init use define_builtin to define
          internal (gimple) builtin BUILT_IN_TRAP.
	* gm2/gm2-gcc/m2except.c:  reformatted slightly.  Bugfix to do_throw
          to ensure that gm2_eh_int_type which is declared globally is
          unshared for each and every use.
	* gm2/gm2-gcc/m2expr.c:  corrected dates and removed trailing space.
	* gm2/gm2-gcc/m2statement.c:  Bugfix to allow nested functions to
          compile.  If a nested function is complete create a cgraph_node
	  (and it will be finalized later), else finalize_function now.
	* gm2/gm2builtins.c:  file changed (it is unused and will be purged).
	* gm2/gm2except.c:  file changed (it is unused and will be purged).

2016-05-23  Gaius Mulley  <gaius@gnu.org>

2016-05-17  Gaius Mulley  <gaius@gnu.org>

	* gm2/bnf/mc-5.bnf:  introduce func fixups.  Removed all
          constant expression procedures.  Removed all type
          generation procedures.  Removed all import processing
          as this should be done in previous passes.

2016-05-16  Gaius Mulley  <gaius@gnu.org>

	* gm2/Make-lang.in:  added mcp5.mod to be built and linked into mc.
          Removed SysExceptions from being built as part of the bootstrap
          for mc.  mc does not need it as SysExceptions is a gm2 runtime
          library.  Removed reference to m2flex.def in MC-DEFS.  Removed
          mcflex.mod from MC-MODS.
	* gm2/init/mcinit:  added mcp5 to be linked and initialised.
	* gm2/mc/README:  corrected the pass description, now that pass 3
          is used by .def and .mod files.  Thus there is no need for pass 6.
          Pass 5 functionality now contains the old pass 6 description.
	* gm2/mc/decl.mod:  new kind funcfixup to allow fixups to be applied
          between constant functions and their parameters (possibly types).
          (eg. MAX(typename)).  Created a fixupInfo record which is used by
          enum fixups and constant function fixups.
	* gm2/mc/mcComp.mod:  enable pass 5.
	* At this point mc should handle constants, all data types and
          generate a tree of nodes representing them.  All procedure prototypes
          are known.  All that is left to do is build a tree of nodes
          representing the code and then walk the tree generating
	  C11 or C++ code.

2016-05-11  Gaius Mulley  <gaius@gnu.org>

	  as a debugging aid.  tempName returns a String.
          makeIntermediateType new procedure function.
          simplifyType call tempName and makeIntermediateType.
          doSimplifyNode also simplifies pointer types.
          outDeclsDefC outputs constants, types and then variables.
          walkPointer returns completed if the type is partial or done.
          walkVarientField returns partial if field type is on the partialQ.
          tryPartial moves pointer types.
          outputPartial moves over pointer types and issues '*' accordingly.

          definition module scope is visible below the implementation
          module.  Use Qualident rather than PushQualident for non
	  data structure based rules.
	* gm2/mc/decl.def:  hasHidden, foreachModModuleDo, paramEnter,
          paramLeave (new procedures).  addImportedModule changed to include
