109 custom tmpfile and tmpname which may use $TMP, $TEMP.
110 all the calls to OS/2 API wrapped so that it is safe to use
111 them under DOS (may die(), though).
112 Tested that popen works under DOS with modified PDKSH and RSX.
113 File::Copy works under DOS.
114 MakeMaker modified to work under DOS (perlmain.c.tmp and sh -c true).
117 OS2::PrfDB exports symbols as documented;
118 should work on OS/2 2.1 again.
119 uses reliable signals when spawing.
120 do not use popen() any more - no intermediate shell unless needed.
123 Functions emx_{malloc,realloc,calloc,free} are exported from DLL.
124 get_sysinfo() bugs corrected (flags were not used and wrongly defined).
127 _isterm is substituted instead of isatty, s?random instead of srand.
128 `register' disabled if -DDEBUGGING and not AOUT build: stupid SD386.
129 3-argument select() was stomping over memory.
132 Can start scripts by executing 'dir/script' and
133 'script.sh'. Form without extension will call shell only if
134 the specified file exists (will not look on path) (to prohibit
135 trying to run shell commands directly). - Needed by magic.t.
138 ALTERNATE_SHEBANG="extproc " supported, thus options on this
139 line are processed (possibly twice). -S is made legal on such
140 a line. This -S -x is not needed any more.
141 perl.dll may be used from non-EMX programs (via PERL_SYS_INIT
142 - the caller should have valid variable "env" with
143 environment). Known problems: $$ does not work - is 0, waitpid
144 returns immediately, thus Perl cannot wait for completion of
148 flock emulation added (disable by setting env PERL_USE_FLOCK=0),
149 thanks to Rocco Caputo;
150 RSX bug with missing waitpid circomvented;
151 -S bug with full path with \ corrected.
154 -S switch to perl enables a search with additional extensions
155 .cmd, .btm, .bat, .pl as well. This means that if you have
156 mycmd.pl or mycmd.bat on PATH,
158 will work. Perl will also look in the current directory first.
159 Moreover, a bug with \; in PATH being non-separator is fixed.
162 $^E tracks calls to CRT now. (May break if Perl masks some
164 $0 may be edited to longer lengths (at least under OS/2).
165 OS2::REXX->loads looks in the OS/2-ish fashion too.
168 Minimal thread support added. One needs to manually move pthread.h
