Set the m4 -I include accordingly to have the folllowing:
- the directory of the parser.
- include/ in the top-level source tree of the current target
(eg, src/finiteVolume/include-m4/ when compiling libfiniteVolume)
- include/ from OpenFOAM
Additional -dry-run option for makeParser, wrap-lemon for expanding m4
only.
Extend m4 wrapping support to include bison as well.
- add additional rule (ending '.ll') for the combination of
flex for C-code but compiling the result as C++.
This can be needed for re-entrant parsers.
- update bison rule to handle renaming of skeleton files.
Use a wrap-bison script to manage this.
