       Subject: [PATCH bleedperl] File::Spec 0.82 beta
       Message-Id: <200006281535.LAA21095@jester.slaysys.com>

       tweak perlembed for multiplicity/usethreads sanity; correct notes
       about Windows

       localize %INC in a Safe compartment so that use/require work
       (many other magic globals probably need similar treatment)

       dounwind() may cause POPSUB() to diddle the wrong PL_curpad
       when @_ is modified, causing coredumps

       slurp mode fix in change#4736 still not quite right

       Point to perlipc for more SysV IPC examples.

       Elaborate POSIX.pod.  Still needs work.

       fix ~320 byte memory leak (psig_{ptr,name} tables were never freed)

       fix large memory leak that has been around for ever, masked by
       -DPURIFY (most of the arenas were never freed!)

       fix memory leak on Windows (PL_sys_intern contents were never
       freed)

       PERL_OBJECT build tweak

       adjust change#6299

       remove rel2abs prototypes (from Barrie Slaymaker)

       missing perldiag entry for unpack("w",...) diagnostic (from
       Andreas Koenig)

       better diagnostic on Frob->stuff() when Frob:: doesn't exist
       (from Richard Soderberg <rs@oregonnet.com>)

       Win32 patches for cfgperl from Sarathy.

       b.t fails under OS/2 (from Yitzchak Scott-Thoennes)

       More POSIX.pod embellishment.

       tyop in change#6306
