[cmucl-cvs] CMUCL commit: src/lisp (x86-validate.h)

[Raymond Toy]

    Date: Saturday, December 18, 2010 @ 11:16:48
  Author: rtoy
    Path: /project/cmucl/cvsroot/src/lisp

Modified: x86-validate.h

On Darwin, SIGSTKSZ is 128K, not 8K like on most other systems.
Adjust the CONTROL_STACK_SIZE and SIGNAL_STACK_START appropriately.
