dfcb750656 Bill's example is still not enough to repro this, but it has other issues that 
seem significant as well.

eca47fe7df Providing --with-ocaml-libdir for ./configure. The default is the 
stdlib if it's beneath --prefix, and is libdir/ocaml otherwise.

If someone has a better way than this to test whether $B is a path
within $A, I'd love to hear it:

  if test "$A" \< "$B" -a "$B" \< "${A}~"

2a0b2ab2fc Constant fold int-to-long-double conversions; 
use APFloat for int-to-float/double; use
round-to-nearest for these (implementation-defined,
seems to match gcc).

2b019da6b0 Collector is the base class for garbage collection code generators. 
This version enhances the previous patch to add root initialization
as discussed here:

http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20070910/053455.html

Collector gives its subclasses control over generic algorithms:

  unsigned NeededSafePoints; //< Bitmask of required safe points.
  bool CustomReadBarriers;   //< Default is to insert loads.
  bool CustomWriteBarriers;  //< Default is to insert stores.
  bool CustomRoots;          //< Default is to pass through to backend.
  bool InitRoots;            //< If set, roots are nulled during lowering.

It also has callbacks which collectors can hook:

  /// If any of the actions are set to Custom, this is expected to
  /// be overriden to create a transform to lower those actions to
  /// LLVM IR.
  virtual Pass *createCustomLoweringPass() const;

  /// beginAssembly/finishAssembly - Emit module metadata as
  /// assembly code.
  virtual void beginAssembly(Module &M, std::ostream &OS,
                             AsmPrinter &AP,
                             const TargetAsmInfo &TAI) const;
  virtual void finishAssembly(Module &M,
                              CollectorModuleMetadata &CMM,
                              std::ostream &OS, AsmPrinter &AP,
                              const TargetAsmInfo &TAI) const;  

Various other independent algorithms could be implemented, but were
not necessary for the initial two collectors. Some examples are
listed here:
