refactor headers, especially alltypes.h, and improve C++ ABI compat the arch-specific bits/alltypes.h.sh has been replaced with a generic alltypes.h.in and minimal arch-specific bits/alltypes.h.in. this commit is intended to have no functional changes except: - exposing additional symbols that POSIX allows but does not require - changing the C++ name mangling for some types - fixing the signedness of blksize_t on powerpc (POSIX requires signed) - fixing the limit macros for sig_atomic_t on x86_64 - making dev_t an unsigned type (ABI matching goal, and more logical) in addition, some types that were wrongly defined with long on 32-bit archs were changed to int, and vice versa; this change is non-functional except for the possibility of making pointer types mismatch, and only affects programs that were using them incorrectly, and only at build-time, not runtime. the following changes were made in the interest of moving non-arch-specific types out of the alltypes system and into the headers they're associated with, and also will tend to improve application compatibility: - netdb.h now includes netinet/in.h (for socklen_t and uint32_t) - netinet/in.h now includes sys/socket.h and inttypes.h - sys/resource.h now includes sys/time.h (for struct timeval) - sys/wait.h now includes signal.h (for siginfo_t) - langinfo.h now includes nl_types.h (for nl_item) for the types in stdint.h: - types which are of no interest to other headers were moved out of the alltypes system. - fast types for 8- and 64-bit are hard-coded (at least for now); only the 16- and 32-bit ones have reason to vary by arch. and the following types have been changed for C++ ABI purposes; - mbstate_t now has a struct tag, __mbstate_t - FILE's struct tag has been changed to _IO_FILE - DIR's struct tag has been changed to __dirstream - locale_t's struct tag has been changed to __locale_struct - pthread_t is defined as unsigned long in C++ mode only - fpos_t now has a struct tag, _G_fpos64_t - fsid_t's struct tag has been changed to __fsid_t - idtype_t has been made an enum type (also required by POSIX) - nl_catd has been changed from long to void * - siginfo_t's struct tag has been removed - sigset_t's has been given a struct tag, __sigset_t - stack_t has been given a struct tag, sigaltstack - suseconds_t has been changed to long on 32-bit archs - [u]intptr_t have been changed from long to int rank on 32-bit archs - dev_t has been made unsigned summary of tests that have been performed against these changes: - nsz's libc-test (diff -u before and after) - C++ ABI check symbol dump (diff -u before, after, glibc) - grepped for __NEED, made sure types needed are still in alltypes - built gcc 3.4.6

make brace placement in public header struct definitions consistent placing the opening brace on the same line as the struct keyword/tag is the style I prefer and seems to be the prevailing practice in more recent additions. these changes were generated by the command: find include/ arch/*/bits -name '*.h' \ -exec sed -i '/^struct [^;{]*$/{N;s/\n/ /;}' {} + and subsequently checked by hand to ensure that the regex did not pick up any false positives.

adjust utmpx struct layout for time64, 32-/64-bit arch compat since time64 switchover has changed the size and layout of the struct anyway, take the opportunity to fix it up so that it can be shared between 32- and 64-bit ABIs on the same system as long as byte order matches. the ut_type member is explicitly padded to make up for m68k having only 2-byte alignment; explicit padding has no effect on other archs. ut_session is changed from long to int, with endian-matched padding. this affects 64-bit archs as well, but brings the type into alignment with glibc's x86_64 struct, so it should not break software, and does not break on-disk format. the semantic type is int (pid-like) anyway. the padding produces correct alignment for the ut_tv member on 32-bit archs that don't naturally align it, so that ABI matches 64-bit. this type is presently not used anywhere in the ABI between libc and libc consumers; it's only used between pairs of consumers if a third-party utmp library using the system utmpx.h is in use.

void updwtmpx(const char *, const struct utmpx *);
add declarations for utmpname/utmpxname to appropriate headers commit 378f8cb5222b63e4f8532c757ce54e4074567e1f added these functions (as stubs) but left them without declarations. this broke some autoconf based software that detected linkability of the symbols but didn't check for a declaration.
