(thanks to Jerry James) + * enhancement: ASDF systems can now depends on SB-QUEUE. * fixes and improvements related to Unicode and external formats: ** bug fix: error handling and restart usage in the ucs-2 external format has been improved. ** there is now an implementation of the ucs-4 external format. ** the utf-16 and utf-32 external formats are supported. + * bug fix: SB-POSIX wrapper for putenv no longer tries to put lisp strings + in the environment. setenv() and unsetenv() are also provided. (reported by + Fare Rideau; launchpad bug lp#460455) + * bug fix: LOAD of both .fasl and .FASL type files now forces fasl-style + loading. This ensures sensible errors for .FASL files from other + implementations on case-insensitive filesystems. (reported by Willem + Broekema; launchpad bug lp#489417) * bug fix: #p"\\\\" can now be read without error on Win32. (reported by Willem Broekema; launchpad bug lp#489698). * bug fix: some minor code rearrangements to reenable warning-free building
