[armedbear-cvs] r14167 - trunk/abcl

[mevenson at common-lisp.net]

Author: mevenson
Date: Sun Oct  7 01:14:24 2012
New Revision: 14167

Log:
Be more aggressive in the default build options.

Copy 'abcl.properties.in' to have these defaults kick in during ABCL
runtime builds.

Always perform incremental compilations of the ABCL runtime.

Optimize runtime wrappers for contemporary 64bit ORCL Hotspot JVM
implementations.
