If SHELL_BUILTIN is defined (as will be the case when building external
...
builtins such as the printf command), then hide a few declarations.
This allows the shell to build again, fixing a problem with
"error" being declared as a function here, and as a variable in
.../usr.bin/printf/printf.c.

* 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.

Make the -s flag of fc work correctly. Ensure that only one command is specified

and ensure that we break out of the loop after executing it.
With the previous code, because the re-executed command was added to the
history, it would think that it still had to execute it, leading to an infinite
loop.
The last thing which differs from ksh is that we get the "fc -s " command into
the history, but this is actually rather a feature in my humble opinion.
To test:
$ echo hello
$ fc -s ec
