Updating UnderC C/C++ interpreter and reduce/reduce conflicts |

Hello !
I'm trying to revive the open source UnderC C/C++ interpreter and make it
compilable with modern compilers, I managed to solve the compilation problem
on windows with mingw, with vc++ 2008 it compiles but crash and the same
happens on linux but interesting enough if I compile then with for debug
both seems to work, but the last is another issue.
Sources that works with mingw on windows are availlable at
https://code.google.com/p/underc-fltk/, the grammar itself is at
https://code.google.com/p/underc-fltk/source/browse/trunk/underc-dad/src/parser.y.
By works I mean they compile and works for most of the C/C++ grammar, some
things that doesn't work and are present on the grammar are:
- "unsigned some_var_name;" although "unsigned int somve_var_name;" works
- "friend class some_class_name;" doesn't work although it's on the grammar
- "typedef (some_func_type_name)(any_arguments);" although "typedef
(*some_func_type_name)(any_arguments);" does work (pointer to function type)
It seems that the problem derives from the reduce/reduce conflicts that some
modification to the grammar in the past could introduced.
Thanks in advance to any help !
My question here is how I can solve the reduce/reduce conflicts in it's
grammar , they seem to have a common root:
State 93 conflicts: 1 shift/reduce, 1 reduce/reduce
State 387 conflicts: 1 shift/reduce, 1 reduce/reduce
State 424 conflicts: 2 shift/reduce, 94 reduce/reduce
State 452 conflicts: 1 shift/reduce, 1 reduce/reduce
