Thanks for looking into this. I have some questions about the c-ctype
changes. It appears that the proposed patch defers to the system
functions (which use the current locale), but that's not the intent of
c-ctype: it's supposed to correspond to a stripped down POSIX "C" locale
regardless of the current locale settings. Is there something special
in z/OS that requires using the system functions? (E.g., does the "C"
locale behave differently depending on some *other* setting regarding
character set?)
With the above in mind, it's not clear what c_isascii should do. Should
it return 1 for bytes in the range 0..127, or for bytes that correspond
to ASCII bytes if one assumes the standard translation from EBCDIC code
page 037 to ASCII? (Is there a standard?) If the former, the current
code is OK; if the latter, does the system isascii always return the
same results regardless of locale and do these results make sense?
Anyway, in looking through the code I see that it's hard to test a port
to EBCDIC because it uses ifdef rather than if, and I do see some
promotion bugs that you noted but we can fix these with inline functions
rather than macros (cleaner and safer nowadays), and there are a few
other style glitches (e.g., boolean values, overuse of >=) so I
installed the attached patch. This patch assumes EBCDIC control
characters are either less than ' ' or are all 1 bits, which I think is
right. The patch also tightens up the tests a bit.
This patch doesn't address the isascii problem, nor the "something
special in z/OS" problem, so quite possibly further patches will be
needed to this module.

Subject: [PATCH] c-ctype: port better to EBCDIC
Problems reported by Daniel Richard G. in
http://lists.gnu.org/archive/html/bug-gnulib/2015-09/msg00020.html
* lib/c-ctype.c: Include <limits.h>, for CHAR_MIN and CHAR_MAX.
Include "verify.h".
(C_CTYPE_ASCII, C_CTYPE_CONSECUTIVE_DIGITS)
(C_CTYPE_CONSECUTIVE_LOWERCASE, C_CTYPE_CONSECUTIVE_UPPERCASE):
Define as enum constants with value false, if not defined, so that
code can use 'if' instead of 'ifdef'. Using 'if' helps make the
code more portable, as both branches of the 'if' are compiled on
all platforms.
(C_CTYPE_EBCDIC): New constant.
(to_char): New static function.
(c_isalnum, c_isalpha, c_isdigit, c_islower, c_isgraph, c_isprint)
(c_ispunct, c_isupper, c_isxdigit, c_tolower, c_toupper):
Rewrite to use 'if' instead of 'ifdef'.
Use to_char if non-ASCII. Prefer <= to >=.
Prefer true and false to 1 and 0, for booleans.
(c_iscntrl): Use 'if', not 'ifdef'. Special case for EBCDIC.
Verify that the character set is either ASCII or EBCDIC.
* tests/test-c-ctype.c: Include <limits.h>, for CHAR_MIN
(to_char): New function.
(test_all): Port to EBCDIC. Add some more tests, e.g., for c_ispunct.
