We here at Siemens (ZFE IS SOF 31) are planning to build a translator
using the Unix-tools yacc and lex. This translator must be capable of
reading any C++-source, creating a symbol table during the translation,
and adding some new code to the original sources. Since yacc does only
provide synthesized attributes, the following questions arise:

  - Is it possible to develop a complete translator
      using only synthesized attributes ?
  - If this is not the case, how can we simulate
      inherited attributes ?

all suggestions and hints are welcome

which is what most C compilers do for value numbering and the like. -John]
