Don't cast pointers to int, but to unsigned long for the health of 64-bit systems. * sunrpc/svc_udp.c: Define MAX only if we don't have it yet. Many system's <sys/param.h> pulls this in. * sysdeps/generic/dl-cache.c: Kill the bottom half of the patch doubled file. * sysdeps/generic/pty.c (forkpty): Get login_tty decl from <utmp.h> instead of defining it locally. * sysdeps/posix/sigvec.c: Prototype wrapper_handler and convert_mask. * sysdeps/stub/chflags.c: Prototype chflags. * sysdeps/stub/fchflags.c: Prototype fchflags. * sysdeps/stub/sstk.c: Prototype sstk. * sysdeps/unix/alpha/sysdep.S: Add strong alias from errno variable to __errno.

Make nextafter, nexttoward set errno (bug 6799). nextafter and nexttoward fail to set errno on overflow and underflow. This patch makes them do so in cases that should include all the cases where such errno setting is required by glibc's goals for when to set errno (but not all cases of underflow where the result is nonzero and so glibc's goals do not require errno setting).

Use libm_alias_double in math/. This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_double to define public function names, in cases where it would be appropriate to define _Float64 / _Float32x aliases for those functions as well. This eliminates many NO_LONG_DOUBLE conditionals and ldbl-opt wrappers round these function implementations. Tested for x86_64. Also tested with build-many-glibcs.py. Binary differences seen are that the different order in which remainder and drem symbols get defined as a result of this patch (the same source file defines the same aliases, but in a different order of definition) changes the order of symbols in the final libm.so when long double = double, and for ldbl-opt configurations, the compat symbols for Bessel functions were previously defined by e.g. "compat_symbol (libm, j0, j0l, GLIBC_2_0)", which declares j0l as a compat symbol based on j0 and so makes j0l weak because j0 is weak, and are now defined (indirectly via the relevant macros) based on e.g. __j0, so are no longer weak because __j0 isn't weak. * math/s_fma.c: Include <libm-alias-double.h>.

Consistently use uintN_t not u_intN_t in libm. This patch changes libm code to make consistent use of C99 uintN_t types instead of sometimes using those and sometimes using the older nonstandard u_intN_t names. This makes sense as a cleanup in its own right, and also facilitates merges to GCC's libquadmath (which gets the types from stdint.h and so may not have u_intN_t available at all). Tested for x86_64, and with build-many-glibcs.py. * math/s_nextafter.c (__nextafter): Use uintN_t instead of u_intN_t. * math/s_nexttowardf.c (__nexttowardf): Likewise. * sysdeps/generic/math_private.h (ieee_double_shape_type): Likewise.

Fix nextafter overflow in non-default rounding modes (bug 16677). ISO C requires the result of nextafter to be independent of the rounding mode, even when underflow or overflow occurs. This patch fixes the bug in various nextafter implementations that, having done an overflowing computation to force an overflow exception (correct), they then return the result of that computation rather than an infinity computed some other way (incorrect, when the overflowing result of arithmetic with that sign and rounding mode is finite but the correct result is infinite) - generally by falling through to existing code to return a value that in fact is correct for this case (but was computed by an integer increment and so without generating the exceptions required). Having fixed the bug, the previously deferred conversion of nextafter testing in libm-test.inc to ALL_RM_TEST is also included. Tested x86_64 and x86; also spot-checked results of nextafter tests for powerpc32 and mips64 to test the ldbl-128ibm and ldbl-128 changes. (The m68k change is untested.)

Use libm_alias_double in math/. This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_double to define public function names, in cases where it would be appropriate to define _Float64 / _Float32x aliases for those functions as well. This eliminates many NO_LONG_DOUBLE conditionals and ldbl-opt wrappers round these function implementations. Tested for x86_64. Also tested with build-many-glibcs.py. Binary differences seen are that the different order in which remainder and drem symbols get defined as a result of this patch (the same source file defines the same aliases, but in a different order of definition) changes the order of symbols in the final libm.so when long double = double, and for ldbl-opt configurations, the compat symbols for Bessel functions were previously defined by e.g. "compat_symbol (libm, j0, j0l, GLIBC_2_0)", which declares j0l as a compat symbol based on j0 and so makes j0l weak because j0 is weak, and are now defined (indirectly via the relevant macros) based on e.g. __j0, so are no longer weak because __j0 isn't weak. * math/s_fma.c: Include <libm-alias-double.h>.

Don't cast pointers to int, but to unsigned long for the health of 64-bit systems. * sunrpc/svc_udp.c: Define MAX only if we don't have it yet. Many system's <sys/param.h> pulls this in. * sysdeps/generic/dl-cache.c: Kill the bottom half of the patch doubled file. * sysdeps/generic/pty.c (forkpty): Get login_tty decl from <utmp.h> instead of defining it locally. * sysdeps/posix/sigvec.c: Prototype wrapper_handler and convert_mask. * sysdeps/stub/chflags.c: Prototype chflags. * sysdeps/stub/fchflags.c: Prototype fchflags. * sysdeps/stub/sstk.c: Prototype sstk. * sysdeps/unix/alpha/sysdep.S: Add strong alias from errno variable to __errno.
