CVS commit: src/bin/sh/bltin

[Alan Barrett <apb%netbsd.org@localhost>]

Module Name:    src
Committed By:   apb
Date:           Sat Mar 29 09:55:40 UTC 2008

Modified Files:
        src/bin/sh/bltin: bltin.h

Log Message:
* define SHELL_BUILTIN, which other headers may use to hide some of their
  symbols if appropriate.  For example, error.h will use it to hide
  declarations that should not be seen by external builtins such as printf.
* The shell's outfmt() function returns void, but the standard fprintf()
  function returns int.  Similarly for several other functions that are
  redefined via macros in bltin.h.  Add a _RETURN_INT macro to do the
  necessary conversion.
* Delete some declarations that appear in error.h.
* Add comments on some #else/#endif lines.
