Address build errors with clang introduced when smixx was added. e.g.
Online/smixx/src/translator/stack.cxx:19:18: error: addition of default argument on redeclaration makes this constructor a default constructor Stack::Stack(int size = 1000) : _maxLen(size), _top(EMPTY) ^ ~~~~ Online/smixx/src/translator/stack.hxx:16:2: note: previous declaration is here Stack(int size); ^ 2 warnings and 1 error generated.
note there are a number of additional warnings with clang, not addressed here. A number look potentially concerning so probably worth investigating.
