* signal/signal.h <__USE_BSD || __USE_XOPEN_EXTENDED>: Define __need_size_t and include stddef.h. * sysvipc/sys/msg.h: Likewise. * posix/sched.h: Likewise. * hurd/hurd/signal.h (__need_size_t): Define. * CONFORMANCE: ctype.h and wctype.h no longer define size_t, neither does signal.h in pedantic ISO C namespaces. stdio.h no longer defines wint_t or wchar_t.

/* The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
|
|
macros for each of the OS types we define below. The definitions
|
|
of those macros must use the following macros for underlying types.
|
|
We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
|
|
variants of each of the following integer types on this machine.
|
|
|
|
16 -- "natural" 16-bit type (always short)
|
|
32 -- "natural" 32-bit type (always int)
|
|
64 -- "natural" 64-bit type (long or long long)
|
|
LONG32 -- 32-bit type, traditionally long
|
|
QUAD -- 64-bit type, always long long
|
|
WORD -- natural type of __WORDSIZE bits (int or long)
|
|
LONGWORD -- type of __WORDSIZE bits, traditionally long
|
|
|
|
We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
|
|
conventional uses of `long' or `long long' type modifiers match the
|
|
types we define, even when a less-adorned type would be the same size.
|
|
This matters for (somewhat) portably writing printf/scanf formats for
|
|
these types, where using the appropriate l or ll format modifiers can
|
|
make the typedefs and the formats match up across all GNU platforms. If
|
|
we used `long' when it's 64 bits where `long long' is expected, then the
|
|
compiler would warn about the formats not matching the argument types,
|
|
and the programmer changing them to shut up the compiler would break the
|
|
program's portability.
|
|
|
|
Here we assume what is presently the case in all the GCC configurations
|
|
we support: long long is always 64 bits, long is always word/address size,
|
|
and int is always 32 bits. */
