Based on schilytools release from 2019-10-25.
Changelog
=========
- include/schily/wchar.h: Some fallback definitions for
mbsinit() mbrtowc() wcrtomb() have been moved to make them always
visible and not only in case that <wchar.h> exists.
- include/schily/wchar.h: Before, we checked for HAVE_ISWPRINT to catch
the HP-UX-10.20 case where wchar_t is in stdlib.h. Now we check
(SIZEOF_WCHAR == 0 || SIZEOF_WCHAR_T == 0) as this works on Ultrix as
well.
- libgetopt: The getopt() function now supports options in the form:
+o, ++long-option or +long-option
if the optstring starts with a '+'. A new exported variable
"optflags" has the bit "OPT_PLUS" set, in case that an actual option
starts with '+'.
If more than one of the flag characters ':', '+' or "()" are used,
"()" must be last.
- Bourne Shell: The testsuite no longer tries to check ISO-8859-1 strings
as we cannot set this up reliably on all platforms and as Mac OS does
not allow to create the related filenames.
- Bourne Shell: The getopts(1) builtin command now supports options in.
the form:
+o, ++long-option or +long-option
if the optstring starts with a '+'. The shell variable "$NAME" has
a leading '+' in case that an actual option starts with '+'.
Note that this makes getopts(1) in the Bourne Shell compatible at
shell script level to the extensions in the getopts(1) implementation
in ksh93 for:
-o/+o Short options with either a leading - or +
--long GNU style long options as aliases to short -o options
++long GNU style long options as aliases to short +o options
Our enhancements to support:
-long UNIX style long options as aliases to short -o options
+long UNIX style long options as aliases to short +o options
- Long options the have no related short option
Are not supported by ksh93.
