* The problem is: currently our single byte ctype(3) functions are brokenache2007-10-131-1/+34
| | | | | | | | | | | | | | | | | | | | | | | | | for wide characters locales in the argument range >= 0x80 - they may return false positives. Example 1: for UTF-8 locale we currently have: iswspace(0xA0)==1 and isspace(0xA0)==1 (because iswspace() and isspace() are the same code) but must have iswspace(0xA0)==1 and isspace(0xA0)==0 (because there is no such character and all others in the range 0x80..0xff for the UTF-8 locale, it keeps ASCII only in the single byte range because our internal wchar_t representation for UTF-8 is UCS-4). Example 2: for all wide character locales isalpha(arg) when arg > 0xFF may return false positives (must be 0). (because iswalpha() and isalpha() are the same code) This change address this issue separating single byte and wide ctype and also fix iswascii() (currently iswascii() is broken for arguments > 0xFF). This change is 100% binary compatible with old binaries. Reviewied by: i18n@

* There is a problem in that one cannot use ctype.h at the same time as partsobrien2000-02-081-31/+31
| | | | | | | | | | | | | | of the C++ stdlib. Our ctype.h uses symbols of the form _<X> to denote the various character classes. Our ctype.h also extends the usual ctype.h offering by adding the "_T" (special) class. Problem is parts of the STL also use the symbol "_T" as its parameterized type. These two uses are incompatible. Thus change the form of the symbols used in ctype to something that fixes the current problem and is less likely to cause conflicts in the future.

* Fixed longstanding namespace convolution involving rune_t vs wchar_t.bde1996-05-011-14/+14
| | | | | | | | | | | If _ANSI_SOURCE or _POSIX_SOURCE is defined, then <ctype.h> had to be included before <stddef.h> or <stdlib.h> to get rune_t declared. Now rune_t is declared perfectly bogusly in all cases when <ctype.h> is included. This change breaks similar (but more convoluted) convolutions in the stddef.h in gcc distributions. Ports of gcc should avoid using the gcc headers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix numerous ANSI conformance bugs and other nits. ctype.h: o There were no prototypes behind the macros (conformance bug). o isascii() didn't have enough parentheses (plain bug). o tolower() and toupper were always static inline (conformance bug? You could undef them and take their address, but this gave different addresses in different modules. You couldn't undef them and declare them (correctly) again). <stdio.h>'s treatment of putc() shows one way to handle this problem, but it only works because the putc() macro is allowed to reevaluate its args. I used a hack controlled by _EXTERNALIZE_CTYPE_INLINES_ to get <ctype.h> to generate the code (the previous hack involving _ANSI_LIBRARY_ goes away). This has the advantage that the core of the functions is only written down once and the disadvantage that another layer of functions is required. The extra layer goes away if inline functions are used, leaving only the problem of understanding why there are functions named toupper(), __toupper and ___toupper() as well as a macro named toupper. o Nothing seems to define _USE_CTYPE_LIBRARY_. Eliminate it o Let the user set _USE_CTYPE_INLINE_ and _DONT_USE_CTYPE_INLINE_ for full control over inlining. o The args for the inline functions didn't have enough underscores (conformance bug). o The formatting and ordering was inconsistent (style bug). o TODO: fix conformance bugs brought by including <runetype.h>.
