after 5.003_05:
PERLLIB_PREFIX was not active if it matches an element of @INC
as a whole.
Do not need PERL_SBRK if crtdll-revision is >= 50.
Use -Zsmall-conv if crtdll-revision is >= 50 (in static perl!).
:7: warning: #warning <dirent.h> requires <sys/types.h>
We compile miniperl static. It cannot fork, thus there may be
problems with pipes (since HAS_FORK is in
place). Pipes are required by makemaker.
We compile perl___.exe A.OUT and dynamic. It should be able to
fork.
If we can fork, we my_popen by popen unless "-|". Thus we
write a cooky "-1" into the pid array to indicate
this.
Apparently we can fork, and we can load dynamic extensions
now, though probably not simultaneously.
*DB tests corrected for OS/2 one-user stat[2].
/bin/sh is intercepted and replaced by SH_PATH.
Note that having '\\' in the command line of one-arg `system'
would trigger call via shell.
Segfault with system {'ls'} 'blah'; corrected.
Documentation of OS/2-different features added to main PODs.
New buitins in Cwd::
Cwd::current_drive
Cwd::sys_chdir - leaves drive as it is.
Cwd::change_drive
Cwd::sys_is_absolute - has drive letter and is_rooted
Cwd::sys_is_rooted - has leading [/\\] (maybe
after a drive)
Cwd::sys_is_relative - changes with current dir
Cwd::sys_cwd - Interface to cwd from EMX.
Cwd::sys_abspath(name, dir)
- Really really odious
function. Returns absolute
name of file which would
have 'name' if CWD were 'dir'.
Dir defaults to the current dir.
Cwd::extLibpath [type] - Get/set current value of extended
Cwd::extLibpath_set - library search path.
path [type]
The optional last argument redirects
to END-path if true,
default is to search BEGIN-path.
(Note that some of these may be moved to different
libraries - eventually).
Executables:
perl - can fork, can dynalink (but not simultaneously)
perl_ - can fork, cannot dynalink
perl__ - same as perl___, but PM.
perl___ - cannot fork, can dynalink.
The build of the first one - perl - is rather convoluted, and
requires a build of miniperl_.

after 5.003_07:
custom tmpfile and tmpname which may use $TMP, $TEMP.
all the calls to OS/2 API wrapped so that it is safe to use
them under DOS (may die(), though).
Tested that popen works under DOS with modified PDKSH and RSX.
File::Copy works under DOS.
MakeMaker modified to work under DOS (perlmain.c.tmp and sh -c true).
after 5.003_08:
OS2::PrfDB exports symbols as documented;
should work on OS/2 2.1 again.
uses reliable signals when spawing.
do not use popen() any more - no intermediate shell unless needed.
