* gc.c (Init_stack): stack region is far smaller than usual if pthread is used. * marshal.c (w_extended): singleton methods should not be checked when dumping via marshal_dump() or _dump(). [ruby-talk:85909] * file.c (getcwdofdrv): avoid using getcwd() directly, use my_getcwd() instead. * merged NeXT, OpenStep, Rhapsody ports patch from Eric Sunshine <sunshine@sunshineco.com>. [ruby-core:01596] * marshal.c (w_object): LINK check earlier than anything else, i.e. do not dump TYPE_IVAR for already dumped objects. (ruby-bugs PR#1220) * eval.c (rb_eval): call "inherited" only when a new class is generated; not on reopening. * eval.c (eval): prepend error position in evaluating string to * configure.in: revived NextStep, OpenStep, and Rhapsody ports which had become unbuildable; enhanced --enable-fat-binary option so that it accepts a list of desired architectures (rather than assuming a fixed list), or defaults to a platform-appropriate list if user does not provide an explicit list; made the default list of architectures for MAB (fat binary) more comprehensive; now uses -fno-common even when building the interpreter (in addition to using it for extensions), thus allowing the interpreter to be embedded into a plugin module of an external project (in addition to allowing embedding directly into an application); added checks for <netinet/in_systm.h> (needed by `socket' extension) and getcwd(); now ensures that -I/usr/local/include is employed when extensions' extconf.rb scripts invoke have_header() since extension checks on NextStep and OpenStep will fail without it if the desired resource resides in the /usr/local tree; fixed formatting of --help message. * Makefile.in: $(LIBRUBY_A) rule now deletes the archive before invoking $(AR) since `ar' on Apple/NeXT can not "update" MAB archives (see configure's --enable-fat-binary option); added rule for new missing/getcwd.c. * defines.h: fixed endian handling during MAB build (see configure's --enable-fat-binary option) to ensure that all portions of the project see the correct WORDS_BIGENDIAN value (some extension modules were getting the wrong endian setting); added missing constants GETPGRP_VOID, WNOHANG, WUNTRACED, X_OK, and type pid_t for NextStep and OpenStep; removed unnecessary and problematic HAVE_SYS_WAIT_H define in NeXT section. * dir.c: do not allow NAMLEN() macro to trust dirent::d_namlen on NextStep since, on some installations, this value always resolves uselessly to zero. * dln.c: added error reporting to NextStep extension loader since the previous behavior of failing silently was not useful; now ensures that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice on Rhapsody since this header lacks multiple-include protection, which resulted in "redefinition" compilation errors. * main.c: also create hard reference to objc_msgSend() on NeXT platforms (in addition to Apple platforms). * lib/mkmf.rb: now exports XCFLAGS from configure script to extension makefiles so that extensions can be built MAB (see configure's --enable-fat-binary option); also utilize XCFLAGS in cc_command() (but not cpp_command() because MAB flags are incompatible with direct invocation of `cpp'). * ext/curses/extconf.rb: now additionally checks for presence of these curses functions which are not present on NextStep or Openstep: bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(), setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(), wscrl(), wsetscrreg() * ext/curses/curses.c: added appropriate #ifdef's for additional set of curses functions now checked by extconf.rb; fixed curses_bkgd() and window_bkgd() to correctly return boolean result rather than numeric result; fixed window_getbkgd() to correctly signal an error by returning nil rather than -1. * ext/etc/etc.c: setup_passwd() and setup_group() now check for null pointers before invoking rb_tainted_str_new2() upon fields extracted from `struct passwd' and `struct group' since null pointers in some fields are common on NextStep/OpenStep (especially so for the `pw_comment' field) and rb_tainted_str_new2() throws an exception when it receives a null pointer. * ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for platforms such as NextStep and OpenStep which lack strdup(). * ext/socket/getaddrinfo.c: cast first argument of getservbyname(), gethostbyaddr(), and gethostbyname() from (const char*) to non-const (char*) for older platforms such as NextStep and OpenStep. * ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for platforms such as NextStep and OpenStep which lack strdup(); include <netinet/in_systm.h> if present for NextStep and OpenStep; cast first argument of gethostbyaddr() and getservbyname() from (const char*) to non-const (char*) for older platforms. * ext/syslog/syslog.c: include "util.h" for strdup()/ruby_strdup() for platforms such as NextStep and OpenStep which lack strdup(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@5002 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
