changes in sbcl-0.9.19 (1.0.0?) relative to sbcl-0.9.18:
* improvement: floating point modes in effect are now saved in
core, and restored on startup.
+ * improvement: GET-INTERNAL-REAL-TIME now reports the time since
+ startup, not time since first call to GET-INTERNAL-REAL-TIME.
* improvements to the Windows port:
** floating point exceptions are now reported correctly.
** stack exhaustion detection works partially.
+ ** more accurate GET-INTERNAL-REAL-TIME.
changes in sbcl-0.9.18 (1.0.beta?) relative to sbcl-0.9.17:
* enhancement: SB-POSIX now supports cfsetispeed(3), cfsetospeed(3),
