Hi,

finally I think I've fixed this bug, it required an overhaul of the
variant code.  The changes have also tidied up some uncleanness.
Anyway it would be interesting to hear if the compiler builds on
cygwin, solaris, OSX now

regards,
Gaius


   * gm2/gm2-compiler/M2CaseList.mod:  tidied up formatting of
     error message.
   * gm2/gm2-compiler/M2GCCDeclare.mod:  IncludeGetParent (New
     function).  Use IncludeGetParent with appropriate symbols.
   * gm2/gm2-compiler/M2Quads.mod:  use GetParent and GetRecord
     together now that the specification for GetParent has
     changed.
   * gm2/gm2-compiler/P2SymBuild.mod:  GetParent now returns the
     parent of the field or variant.  GetRecord returns the
     record of variant.  PutFieldRecord returns the field created
     so that it can be recorded as the tag via PutVariantTag if
     neccesary.  Modified BuildFieldRecord,
     BuildVariantSelector, StartBuildVariantFieldRecord and
     EndBuildVariantFieldRecord.
   * gm2/gm2-compiler/SymbolTable.def:  export GetRecord.
   * gm2/gm2-compiler/SymbolTable.mod:   GetParent now returns
     the parent of the field or variant.  GetRecord returns the
     record of variant.  PutFieldRecord returns the field created
     so that it can be recorded as the tag via PutVariantTag if
     neccesary.  EnsureOrder (New function) used by
     PutVariantTag.
   * gm2/ulm-lib-gm2/std/RTErrors.def:  include two ELSE clauses.
   * gm2/ulm-lib-gm2/std/TimeIO.mod:  include ELSE clause.
