I'm glad you picked up this stuff up, it is part of the few remaining
things to implement for mailx standards compliance. :-D
I've done a quick first pass, comments are inlined.

|
| One little note: SUS is unclear on what does "login-name part of
| the address" means (in -F case). I've decided to use "the
| word before @,!,%", but this is, of course, arguable. For
| example, the only system I know of to support -F, AIX,
| uses the whole address as a filename.
|
This sounds like a good choice.

I would really rather not have the setfile() function duplicated here.
Since the setfile()'s return code is only checked for error in two places,
your modified setfile() should work in those cases as well. So, can you
modify setfile to return a more descriptive error code like in your
checkmail and use it instead for the -e option? Also, the fprintf that
displays "No mail for ..." should not be printed when using the -e option.
SuSv3 states that when using the -e option, nothing should be printed.

pointed at, and submit a new version of the patch.

Well, I've interpreted the phrase "The mailx utility shall write nothing
and exit with a successful return code if there is mail to read" like
that "one should not print anything in "there is mail" case".
Of course, since most prospective use of -e is in scripts, printing
in "no mail" case is, perhaps, futile :)

timezone is defined as a long, a lot of time keeping applications (in
this part of the world at the least) depend on this variable maintaining
the value difference between UTC and the local standard time.
Is there any chance we could move our timezone function to something
else? and stick to a timezone variable? or provide an alternative name
but similar functionality to this? Anyone working on this already?

I think the "no mail" case is valid and we shouldn't print anything.
However, I do believe we should still leave in the err[x]() messages for
fatal conditions.

There's only a single reference to timezone() in the whole source tree,
src/contrib/sendmail/src/arpadate.c, and the code in that file is
#ifdef'ed out. Just for fun I built and installed a world without
timezone(), as expected it succeeded. NetBSD already warns that
timezone() will eventually disappear in its man page, maybe we should
follow them and remove timezone() in 6-current.
Cheers,
Stefan

>Description:
A recent discussion in the newsgroup comp.std.c (Subject: Re: Memory question)
revealed that ISO/IEC 9899:1999 does not allow malloc(0) to return the same
non-null pointer each time it is called.
# 7.20.3 Memory management functions
# The order and contiguity of storage allocated by successive calls to the calloc,
# malloc, and realloc functions is unspecified. The pointer returned if the allocation
# succeeds is suitably aligned so that it may be assigned to a pointer to any type of object
# and then used to access such an object or an array of such objects in the space allocated
# (until the space is explicitly deallocated). The lifetime of an allocated object extends
# from the allocation until the deallocation. Each such allocation shall yield a pointer to an
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
# object disjoint from any other object. The pointer returned points to the start (lowest byte
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
# address) of the allocated space. If the space cannot be allocated, a null pointer is
# returned. If the size of the space requested is zero, the behavior is implementation-
# defined: either a null pointer is returned, or the behavior is as if the size were some
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
# nonzero value, except that the returned pointer shall not be used to access an object.
^^^^^^^^^^^^^
The C89 wording about an "unique pointer" was dropped.
>How-To-Repeat:
This strictly conforming C99 program fails due to malloc()'s non-compliance:
#include <assert.h>
#include <stdlib.h>
int
main(void)
{
void *p, *q;
p = malloc(0);
q = malloc(0);
assert(p != q || p == NULL);
return (0);
}
>Fix:
Either enabling malloc()'s V flag by default or adding
'if (size == 0) size = 1;' should make malloc() compliant.
