[xemacs-hg @ 2005-10-25 08:32:40 by ben] more mc-alloc-related factoring; make it hard to do the wrong thing postgresql/postgresql.c, postgresql/postgresql.h: MC-Alloc refactoring. ldap/eldap.c, ldap/eldap.h: MC-Alloc refactoring. alloc.c, buffer.c, console.c, emacs.c, file-coding.c, lrecord.h, lstream.c, mule-charset.c, print.c, scrollbar-gtk.c, scrollbar-msw.c, scrollbar-x.c, scrollbar.c, symbols.c, symeval.h, unicode.c, window.c, xemacs.def.in.in: rename `struct lcrecord_header' to `struct old_lcrecord_header'; likewise for `old_basic_alloc_lcrecord', `old_free_lcrecord', `old_zero_lcrecord', `old_zero_sized_lcrecord', `old_copy_lcrecord', `old_copy_sized_lcrecord', `old_alloc_lcrecord_type'. Created new LISPOBJ_STORAGE_SIZE() used only on objects created through allocation of Lisp-Object memory instead of basic xmalloc()/xfree(). This is distinguished from malloced_storage_size(), for non-Lisp-Objects. The definition of LISPOBJ_STORAGE_SIZE() can reduce down to malloced_storage_size() when not MC-ALLOC, but with MC-ALLOC it's a different function. The whole point other than cleaning up the use of LISPOBJ_STORAGE_SIZE is to make it harder to accidentally use the old kind (lowercase) of function in new code, since you get a compile error.

/* The d_nameln member of a struct dirent includes the '\0' character
   on some systems, but not on others.  What's worse, you can't tell
   at compile-time which one it will be, since it really depends on
   the sort of system providing the filesystem you're reading from,
   not the system you are running on.  Paul Eggert
   <eggert@bi.twinsun.com> says this occurs when Emacs is running on a
   SunOS 4.1.2 host, reading a directory that is remote-mounted from a
   Solaris 2.1 host and is in a native Solaris 2.1 filesystem.

   (and Solaris 2 doesn't have a d_nameln member at all!  Posix.1
   doesn't specify it -- mrb)

   Since applying strlen to the name always works, we'll just do that.  */
