Revision 1.12.2.6 - (hide annotations)
Thu Jun 29 07:52:30 2000 UTC (13 years, 9 months ago) by dtc
Branch: RELENG_18
CVS Tags: RELEASE_18c
Changes since 1.12.2.5: +6 -1 lines
Blow away the slot-value and slot-boundp compiler-macros exported from
Lisp when bootstrapping from a lisp core that includes PCL. This overcomes
trouble noted compiling Gray streams from a core that includes PCL.
