Add thread-safety to libc, so that libc_r will build (on i386 at least). All POSIX libc api now there (to P1003.1c/D10) (more md stuff is needed for other libc/arch/*) (setlogin is no longer a special syscall) Add -pthread option to gcc (that makes it use -lc_r and -D_POSIX_THREADS). Doc some re-entrant routines Add libc_r to intro(3) dig() uses some libc srcs and an extra -I was needed there. Add more md stuff to libc_r. Update includes for the pthreads api Update libc_r TODO

Use a Thread Information Block in both single and multi-threaded programs. This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable! Make libpthread dlopen'able by moving the cancelation wrappers into libc and doing locking and fork/errno handling via callbacks that libpthread registers when it first initializes. 'errno' *must* be declared via <errno.h> now! Clean up libpthread's symbol exports like libc. On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

# Include link-time warnings about unsafe API uses (ie. strcpy)
turn on APIWARN (prints link-time warnings for a few more functions). The snapshots have been built with this for more than a year, but the releases have not. This is a fair bit more noisy in the ports tree, but it is good advice for people about how they can improve their code. Let us see where the annoyance vs worthwhile balance lands ok pvalchev

Replace the single-byte placeholders for the multi-byte/wide-character conversion interfaces of libc (mbrtowc(3) and friends) with new implementations that internally call an API based on NetBSD's citrus. This allows us to support locales with multi-byte character encodings. Provide two implementations of the citrus-based API: one based on the old single-byte placeholders for use with our existing single-byte character locales (C, ISO8859-*, KOI8, CP1251, etc.), and one that provides support for UTF-8 encoded characters (code based on FreeBSD's implementation). Install the en_US.UTF-8 ctype locale support file, and allow the UTF-8 ctype locale to be enabled via setlocale(3) (export LC_CTYPE='en_US.UTF-8'). A lot of programs, especially from ports, will now start using UTF-8 if the UTF-8 locale is enabled. Use at your own risk, and please report any breakage. Note that ncurses-based programs cannot display UTF-8 right now, this is being worked on. To prevent install media growth, add vfprintf(3) and mbrtowc(3) to libstubs. The mbrtowc stub was copied unchanged from its old single-byte placeholder. vfprintf.c doesn't need to be copied, just put in .PATH (hint by fgsch@). Testing by myself, naddy, sthen, nicm, espie, armani, Dmitrij D. Czarkoff. ok matthieu espie millert sthen nicm deraadt

- replace dtoa w/ David's gdtoa, version 2008-03-15 - provide proper dtoa locks - use the real strtof implementation - add strtold, __hdtoa, __hldtoa - add %a/%A support - don't lose precision in printf, don't round to double anymore - implement extended-precision versions of libc functions: fpclassify, isnan, isinf, signbit, isnormal, isfinite, now that the ieee.h is fixed - separate vax versions of strtof, and __hdtoa - add complex math support. added functions: cacos, casin, catan, ccos, csin, ctan, cacosh, casinh, catanh, ccosh, csinh, ctanh, cexp, clog, cabs, cpow, csqrt, carg, cimag, conj, cproj, creal, cacosf, casinf, catanf, ccosf, csinf, ctanf, cacoshf, casinhf, catanhf, ccoshf, csinhf, ctanhf, cexpf, clogf, cabsf, cpowf, csqrtf, cargf, cimagf, conjf, cprojf, crealf - add fdim, fmax, fmin - add log2. (adapted implementation e_log.c. could be more acruate & faster, but it's good enough for now) - remove wrappers & cruft in libm, supposed to work-around mistakes in SVID, etc.; use ieee versions. fixes issues in python 2.6 for djm@ - make _digittoint static - proper definitions for i386, and amd64 in ieee.h - sh, powerpc don't really have extended-precision - add missing definitions for mips64 (quad), m{6,8}k (96-bit) float.h for LDBL_* - merge lead to frac for m{6,8}k, for gdtoa to work properly - add FRAC*BITS & EXT_TO_ARRAY32 definitions in ieee.h, for hdtoa&ldtoa to use - add EXT_IMPLICIT_NBIT definition, which indicates implicit normalization bit - add regression tests for libc: fpclassify and printf - arith.h & gd_qnan.h definitions - update ieee.h: hppa doesn't have quad-precision, hppa64 does - add missing prototypes to gdtoaimp - on 64-bit platforms make sure gdtoa doesn't use a long when it really wants an int - etc., what i may have forgotten... - bump libm major, due to removed&changed symbols - no libc bump, since this is riding on djm's libc major crank from a day ago discussed with / requested by / testing theo, sthen@, djm@, jsg@, merdely@, jsing@, tedu@, brad@, jakemsr@, and others. looks good to millert@ parts of the diff ok kettenis@ this commit does not include: - man page changes
