[llvm-commits] CVS: llvm/autoconf/configure.ac

[John Criswell]

Changes in directory llvm/autoconf:

configure.ac updated: 1.15 -> 1.16

---
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.
