[LLVMdev] Make dragonegg work with gcc-4.6

[陳韋任]

Hi, Duncan

  I saw you started to port dragonegg to gcc 4.6, which is a good news.
And I am also trying to do that. The attachment get src/Convert.cpp to
compile against gcc-4.6.

  Now I get a error while compiling dragonegg,

---
Compiling Debug.cpp
/tmp/chenwj/dragonegg/src/Debug.cpp: In member function 'llvm::DIType llvm::DebugInfo::createArrayType(tree_node*)':
/tmp/chenwj/dragonegg/src/Debug.cpp:623: error: 'TYPE_DEBUG_REPRESENTATION_TYPE' was not declared in this scope
---

  According to the gcc-4.6.0/gcc/ChangeLog-2010, TYPE_DEBUG_REPRESENTATION_TYPE
had been removed. I am still trying to solve this.

Regards,
chenwj
