is void.
New executables perl___<number> generated with decreased stack size
(good when virtual memory is low; e.g. floppy boot).
+
+After 5.8.2 (@21668):
+ Fixes to installperl scripts to avoid junk output, allow overwrite
+ of existing files (File::Copy::copy is mapped to DosCopy()
+ with flags which would not overwrite).
+ Disable DynaLoading of Perl modules with AOUT build (will core anyway).
+ For AOUT build: Quick hack to construct directories necessary for
+ /*/% stuff [maybe better do it from hints/os2.sh?].
+ AOUT build: do -D__ST_MT_ERRNO__ to simplify linking with -Zmtd
+ (e.g., to test GD: gd.dll linked with -Zmtd).
+ MANIFEST.SKIP was read without a drive part of the filename.
+ Rename Cwd::extLibpath*() to OS2::... (old names still preserved).
+ Install perl.lib and perl.a too.
+ New methods libPath_find(),has_f32(),handle(),fullname() for OS2::DLL.
+ Enable quad support using long long.
+ New C exported functions os2_execname(), async_mssleep(), msCounter(),
+ InfoTable(), dir_subst(), Perl_OS2_handler_install(),
+ fill_extLibpath().
+ async_mssleep() uses some undocumented features which allow usage of
+ highest possible resolution of sleep() while preserving low
+ priority (raise of resolution may be not available before
+ Warp3fp40; resolution is 8ms/CLOCK_SCALE).
+ usleep() and select(undef,undef,undef,$t) are using this
+ interface for time up to 0.5sec.
+ New convenience macros os2win_croak_0OK(rc,msg), os2win_croak(rc,msg),
+ os2cp_croak(rc,msg).
+ Supports ~installprefix, ~exe, ~dll in PERLLIB_PREFIX etc (actual
+ directories are substituted).
+ New functions OS2::msCounter(), OS2::ms_sleep(), OS2::_InfoTable().
+ Checks stack when fixing EMX being under-initialized (-Zomf -Zsys
+ produces 32K stack???).
+ New environment variables PERL_BEGINLIBPATH, PERL_PRE_BEGINLIBPATH,
+ PERL_POST_BEGINLIBPATH, PERL_ENDLIBPATH,
+ PERL_PRE_ENDLIBPATH PERL_POST_ENDLIBPATH (~-enabled);
+ PERL_EMXLOAD_SECS.
+ Better handling of FIRST_MAKEFILE (propagate to subdirs during test,
+ do not require Makefile.PL present).
+ perl2cmd converter: do not rewrite if no change.
+ README.os2 updated with info on building binary distributions and
+ custom perl executables (but not much else).
