extension-full-name and Perl-version mangling work in the
same set ot 576 possible keys, this may lead to clashes).
$^E was reset on the second read, and contained ".\r\n" at the end.

+after 5.005_53:
+ Would segfault system()ing non-existing program;
+ AOUT build was hosed;
+ warning-test for getpriority() might lock the system hard on
+ pre-fixpak22 configuration (calling getpriority() on
+ non-existing process triggers a system-wide bug).
+
+
+ PrfDB was using a bug in processing XSUBs returning U32.
+
+ Variable $OS2::emx_rev implemented (string and numberic values
+ are the same as C variables _emx_rev and _emx_vprt).
+ Variable $OS2::emx_env implemented (same as C variable _emx_env).
+ Variable $OS2::os_ver implemented (_osmajor + 0.001 * _osminor).
+
+ Improved centralized management of HAB and HMQ. To get Perl's
+ HAB, call perl_hab_GET(). (After the initial call one
+ can use Perl_hab instead.) To require Perl's HMQ,
+ call perl_hmq_GET(), to release it call perl_hmq_UNSET(),
+ to obtain it between these calls use Perl_hmq.
+ HMQ management is refcounted, and the program will morph
+ itself into/from PM if required.
+ If perl.h cannot be included, hab may be obtained by Perl_hab_GET().
+
+ New function OS2::Error(do_harderror,do_exception). Returns
+ undef if it was not called yet, otherwise bit 1 is
+ set if on previous call do_harderror was enabled, bit
+ 2 is set if if on previous call do_exception was enabled.
+ This function enables/disables error popups associated with
+ hardware errors (Disk not ready etc.) and software exceptions.
+
+ New function OS2::Errors2Drive(drive). Returns undef if it was
+ not called yet, otherwise return false if Errors were
+ not requested to be written to a hard drive, or the
+ drive letter if this was requested.
+ This function may redirect error popups associated with
+ hardware errors (Disk not ready etc.) and software exceptions
+ to the file POPUPLOG.OS2 at the root directory of the
+ specified drive. Overrides OS2::Error() specified by
+ individual programs. Given argument undef will
+ disable redirection. Has global effect, persists
+ after the application exits.
+
+ New function OS2::SysInfo(). Returns a hash with system information.
+ The keys of the hash are
+
+ MAX_PATH_LENGTH, MAX_TEXT_SESSIONS, MAX_PM_SESSIONS,
+ MAX_VDM_SESSIONS, BOOT_DRIVE, DYN_PRI_VARIATION,
+ MAX_WAIT, MIN_SLICE, MAX_SLICE, PAGE_SIZE,
+ VERSION_MAJOR, VERSION_MINOR, VERSION_REVISION,
+ MS_COUNT, TIME_LOW, TIME_HIGH, TOTPHYSMEM, TOTRESMEM,
+ TOTAVAILMEM, MAXPRMEM, MAXSHMEM, TIMER_INTERVAL,
+ MAX_COMP_LENGTH, FOREGROUND_FS_SESSION,
+ FOREGROUND_PROCESS
+
+ New function OS2::BootDrive(force). Returns a letter without colon.
+
+ New functions OS2::MorphPM(serve)/OS2::UnMorphPM(serve). Transforms
+ the current application into a PM application and back.
+ The argument true means that a real message loop is
+ going to be performed.
+ OS2::MorphPM() returns the PM message queue handle as an integer.
+
+ New function OS2::Serve_Messages(force). Fake on-demand
+ retrieval of outstanding PM messages. If force is false,
+ will not dispatch messages if a real message loop is known to
+ be present. Returns number of messages retrieved.
+ Dies with "QUITing..." if WM_QUIT message is obtained.
+
+ New function OS2::Process_Messages(force [, cnt]). Retrieval
+ of PM messages until window creation/destruction.
+ If force is false, will not dispatch messages
+ if a real message loop is known to be present.
+ Returns change in number of windows. If cnt is given,
+ it is incremented by the number of messages retrieved.
+ Dies with "QUITing..." if WM_QUIT message is obtained.
+
+after 5.005_54:
+ Opening pipes from/to processes could fail if (un)appropriate
+ combination of STDIN/STDOUT was closed.
+
+ If the only shell-metachars of a command are ' 2>&1' at the
+ end of a command, it is executed without calling the external shell.
+
+after 5.005_57:
+ Make UDP sockets return correct caller address (OS2 API bug);
+ Enable TCPIPV4 defines (works with Warp 3 IAK too?!);
+ Force Unix-domain sockets to start with "/socket", convert
+ '/' to '\' in the calls;
+ Make C<system 1, $cmd> to treat $cmd as in C<system $cmd>;
+ Autopatch Configure;
+ Find name and location of g[nu]patch.exe;
+ Autocopy perl????.dll to t/ when testing;
+
+after 5.005_62:
+ Extract a lightweight DLL access module OS2::DLL from OS2::REXX
+ which would not load REXX runtime system;
+ Allow compile with os2.h which loads os2tk.h instead of os2emx.h;
+ Put the version of EMX CRTL into -D define;
+ Use _setsyserror() to store last error of OS/2 API for $^E;
+ New macro PERL_SYS_INIT3(argvp, argcp, envp);
+ Make Dynaloader return info on the failing module after failed dl_open();
+ OS2::REXX test were done for interactive testing (were writing
+ "ok" to stderr);
+ system() and friends return -1 on failure (was 0xFF00);
+ Put the full name of executable into $^X
+ (alas, uppercased - but with /);
+ t/io/fs.t was failing on HPFS386;
+ Remove extra ';' from defines for MQ operations.
