$0 may be edited to longer lengths (at least under OS/2).
OS2::REXX->loads looks in the OS/2-ish fashion too.
+after 5.004_04:
+ Default perl.exe was built with a shorter stack than expected.
+ Strip extensions DLLs too (unless debugging build).
+ ./os2.c being RO could stop cp.
+ When starting scripts, Perl will find them on path (using the same
+ extensions as for -S command-line switch). If it finds magic
+ `extproc ' or `#!' cookies, it will start the scripts directly.
+ May use `cmd /c more <' as a pager.
+ If a program could not be started, this might have been hidden.
+ End of pipe was closed twice when `open'ing a pipeline.
+
after 5.004_53:
Minimal thread support added. One needs to manually move pthread.h
+
+after 5.004_64:
+ Make DLL names different if thread-enabled.
+ Emit more informative internal DLL descriptions.
