* Delete the stubs of the XK_EXE mechanism that was never implemented.
From a security, stability, and simplicity perspective, i would
consider implementing it a truly terrible idea, so let's better
get rid of it.
* Do not use the local variable "num" in el_wgets() alternately for
two completely different purposes. Only use it for the number
of characters read, as stated in the comment (or -1 as long as
that number is still unknown), not for the (more or less boolean)
return value of read_getcmd(). Actually, there is no need at
all to save the latter return value after testing it once.
* The function read_getcmd() has very unusual return values:
It returns -1 for success and 0 for EOF/error. Switch that around
to 0 for success and -1 for EOF/error to be less confusing, and
get rid of the OKCMD preprocessor macro.
* Get rid of one #ifdef section in el_wgets() by using
el->el_chared.c_macro directly at the only place
where it is used.
* Delete the unused MIN() macro.
- The file tokenizer.c no longer uses chartype.h,
so don't include the header.
- The dummy definitions of ct_{de,en}code_string() for the
NARROWCHAR case are only used in history.c, so move them there.
- Now the whole content of chartype.h is for the wide character
case only. So remove the NARROWCHAR ifdef and include the
header only in the wide character case.
- In chartype.h, move ct_encode_char() below the comment explaining it.
- No more need for underscores before ct_{de,en}code_string().
- Make the conversion buffer resize functions private.
They are only called from the decoding and encoding functions
inside chartype.c, and no need can possibly arise to call them
from anywhere else.
build crtbeginS.o with -O1 as GCC tries to be very smart with the
__DTOR_LIST__ as it believes it knows the size of the array at
compile time (which is not true until link time). on SPARC and
MIPS, the result was emitting a call to 0.
technically, i believe that GCC isn't "wrong" to make this choice,
as the array is declared with a well-known initialiser size in the
crtbegin.c compilation unit, and we have noticed that the libgcc
version of this code has some hacks added, most likely to avoid
being bitten by this optimisation.
this makes sshd work for me on earm and sparc with GCC 5.
