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.
after 5.003_11:
Functions emx_{malloc,realloc,calloc,free} are exported from DLL.
get_sysinfo() bugs corrected (flags were not used and wrongly defined).
after 5.003_20:
_isterm is substituted instead of isatty, s?random instead of srand.
`register' disabled if -DDEBUGGING and not AOUT build: stupid SD386.
3-argument select() was stomping over memory.
after 5.003_21:
Can start scripts by executing 'dir/script' and
'script.sh'. Form without extension will call shell only if
the specified file exists (will not look on path) (to prohibit
trying to run shell commands directly). - Needed by magic.t.
after 5.003_27:
ALTERNATE_SHEBANG="extproc " supported, thus options on this
line are processed (possibly twice). -S is made legal on such
a line. This -S -x is not needed any more.
perl.dll may be used from non-EMX programs (via PERL_SYS_INIT
- the caller should have valid variable "env" with
environment). Known problems: $$ does not work - is 0, waitpid
returns immediately, thus Perl cannot wait for completion of
started programs.
after 5.004_01:
flock emulation added (disable by setting env PERL_USE_FLOCK=0),
thanks to Rocco Caputo;
RSX bug with missing waitpid circomvented;
-S bug with full path with \ corrected.
before 5.004_02:
-S switch to perl enables a search with additional extensions
.cmd, .btm, .bat, .pl as well. This means that if you have
mycmd.pl or mycmd.bat on PATH,
perl -S mycmd
will work. Perl will also look in the current directory first.
Moreover, a bug with \; in PATH being non-separator is fixed.
after 5.004_03:
$^E tracks calls to CRT now. (May break if Perl masks some
changes to errno?)
$0 may be edited to longer lengths (at least under OS/2).
OS2::REXX->loads looks in the OS/2-ish fashion too.
