[ruby-dev:21194] http://www.geocities.co.jp/SiliconValley-PaloAlto/1409/ruby/beos.html * error.c (syserr_eqq): errno might exceed Fixnum limit. * error.c (Init_Exception): moved base initialization from init_syserr(). * inits.c (rb_call_inits): postpone initializing errnos until Bignum is available. * ext/curses/curses.c (_XOPEN_SOURCE_EXTENDED): needed to let keyname() and so on be declared. * ext/curses/curses.c (curses_resizeterm, window_resize): arguments conflicted with macros in term.h. * ext/curses/curses.c (Curses module methods): ensure initialized.
