* The C runtime system now builds with better optimization and many
fewer warnings, thanks to lots of cleanups by Martin Atzmueller.
+changes in sbcl-0.6.10 relative to sbcl-0.6.9:
+
+* A patch from Martin Atzmueller seems to have solved the SIGINT
+ problem, and as far as we know, signal-handling now works cleanly.
+ (If you find any new bugs, please report them!)
+* The system no longer defaults Lisp source file names to types
+ ".l", ".cl", or ".lsp", but only to ".lisp".
+* The compiler no longer uses special default file extensions for
+ byte-compiled code. (The ANSI definition of COMPILE-FILE-PATHNAME
+ seems to expect a single default extension for all compiled code,
+ and there's no compelling reason to try to stretch the standard
+ to allow two different extensions.) Instead, byte-compiled files
+ default to the same extension as native-compiled files.
+* Fasl file format version numbers have increased again, because
+ a rearrangement of internal implementation packages made some
+ dumped symbols in old fasl files unreadable in new cores.
+?? #'(SETF DOCUMENTATION) is now defined.
+* Bug #17 (differing COMPILE-FILE behavior between logical and
+ physical pathnames) has been fixed, and some related misbehavior too,
+ thanks to a patch from Martin Atzmueller.
+* More compiler warnings in src/runtime/ are gone, thanks to
+ patches from Martin Atzmueller.
+* Martin Atzmueller pointed out that bug 37 was fixed by his patches
+ some time ago.
+
planned incompatible changes in 0.7.x:
* The debugger prompt sequence now goes "5]", "5[2]", "5[3]", etc.
