* new feature: on platforms where "dladdr" is available foreign
function names now appear in backtraces. (based on Helmut Eller's
work for CMUCL)
+ * documentation: networking interface SB-BSD-SOCKETS' documentation
+ has been integrated into the user manual.
* bug fix: backtraces involving undefined functions or assembly
routines are more informative. (thanks to Brian Downing)
* bug fix: mutually referent alien structures now work correctly.
