[llvm-commits] CVS: llvm/configure

Changes in directory llvm:

configure updated: 1.23 -> 1.24

---
Log message:

Added code that verifies that the source directory has not been configured
already.  This should help prevent strange errors from happening, but will
make re-configuring the source directory more difficult when it is shared with
the object directory.
