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

[John Criswell]

Changes in directory llvm/autoconf:

configure.ac updated: 1.115 -> 1.116
---
Log message:

Configure Datatypes.h.in with AC_CONFIG_HEADERS.  This should prevent it
from being re-generated if the new version is identical to the old version.
Hence, it should save us some recompiling after re-configures.

Diffs of the changes:  (+4 -14)
