This patch fixed a problem which isn't in newlib, but in projects
incorrectly using symbols from the reserved namespace.
This reverts commit 3ba1bd0d9d.
We're seeing a build failure in GNU sim code which is using _P locally
but the ctype.h define clashes with it. Rename these to use the same
symbols that glibc does. They're a bit more verbose, but seems likely
that we'll have fewer conflicts if glibc isn't seeing them.
However, these shortnames are still used internally by ctype modules
to produce pretty concise source code, so move the short names to the
internal ctype_.h where short name conflicts shouldn't show up.
So far the build mechanism in newlib only allowed to either define
machine-specific headers, or headers shared between all machines.
In some cases, architectures are sufficiently alike to share header
files between them, but not with other architectures. A good example
is ix86 vs. x86_64, which share certain traits with each other, but
not with other architectures.
Introduce a new configure variable called "shared_machine_dir". This
dir can then be used for headers shared between architectures.

The commit 46ba1675c4 accidently changed a
bit-field from signed to unsigned. The caseconv_entry::delta must be a
signed integer, see also "newlib/libc/ctype/caseconv.t".
Unfortunately, a standard GCC/Newlib build is done without
-Wsign-conversion. Using this warning option would have helped to avoid
this bug:
caseconv.t:2:22: warning: unsigned conversion from 'int' to 'unsigned int:17' changes value from '-32' to '131040' [-Wsign-conversion]
{0x0061, 25, TOUP, -32},

Subject: [PATCH] nvptx port
This port adds support for Nvidia GPU's, which are primarily used as
offload accelerators in OpenACC and OpenMP.
E.g. arm ABI requires -fshort-enums for bare-metal toolchains.
Given there are only 29 category enums, the compiler chooses an
8 bit enum type, so a size of 11 bits for the bitfield leads to
a compile time error:
error: width of 'cat' exceeds its type
enum category cat: 11;
^~~
Fix this by aligning the size of the category members to byte
borders.

Scripts do not try to acquire Unicode data by best-effort magic anymore.
Options supported:
-h for help
-i to copy Unicode data from /usr/share/unicode/ucd first
-u to download Unicode data from unicode.org first
If (despite of -i or -u if given) the necessary Unicode files are not
available locally, table generation is skipped, but no error code is
returned, so not to obstruct the build process if called from a Makefile.

touupper and toulower didn't return a value in all cases. Worse,
this only broke Cygwin when building without optimization for debug
purposes.
Why GCC neglects to notice this is a mystery.
While at it, fix formatting.

The tow* functions use an included case conversion table which can be
generated from Unicode data.
The isw* functions use a character categories table (provided by
categories.c) which can be generated from Unicode data.
Delegation between current-locale and specific-locale-dependent functions
was reverted towards the generic locale-dependent functions (*_l.c);
this is however only relevant on systems with non-Unicode wide character
locales, thus not on Cygwin.
Table categories.t and tag enumeration categories.cat provide
character class data for most of the isw* functions.
These data are generated from Unicode data.

_ctype_b is defined in ctype_.c as a const char array for non cygwin
targets allowing negative ctype index but as a char array for the same
targets in ctype_.h, giving type conflict at compile time. This is
because the cygwin targets are not treated specially in the latter file.
This patch adds the necessary logic for cygwin targets in ctype_.h.
Keep __ctype_ptr__ available on Cygwin only, for backward compatibility
with existing apps referencing it via the ctype macros.
Otherwise initialize __global_locale.ctype_ptr and __C_locale.ctype_ptr
and use them throughout.

The former __locale_charset always fetched the current locale's charset.
We need the per-locale charset, too, in future. Rename __locale_charset
to __current_locale_charset and change __locale_charset to take a
locale_t as parameter. Accommodate througout.

make pdf on arm-none-eabi targets fails to build after the reorganization in
baf0c9fcb5 to fold is*_l documentation in their
is* counterpart. This is due two issues:
1) newlib/libc/ctype/ctype.tex still including the def file for the long versions
2) missing angle brackets in .c files for some of is*_l functions
This patch fixes the issues and allows make pdf to succeeds.
Don't use global variables. This allows to call loadlocale from
the yet to be created newlocale().
Rename _thr_locale_t to __locale_t (these locales are not restricted
to threads so the name is misleading).
Along these lines, fix _set_ctype to take a __locale_t as parameter.

- Remove charset parameter from low level __foo_wctomb/__foo_mbtowc calls.
- Instead, create array of function for ISO and Windows codepages to point
to function which does not require to evaluate the charset string on
each call. Create matching helper functions. I.e., __iso_wctomb,
__iso_mbtowc, __cp_wctomb and __cp_mbtowc are functions returning the
right function pointer now.
- Create __WCTOMB/__MBTOWC macros utilizing per-reent locale and replace
calls to __wctomb/__mbtowc with calls to __WCTOMB/__MBTOWC.
- Drop global __wctomb/__mbtowc vars.
- Utilize aforementioned changes in Cygwin to get rid of charset in other,
calling functions and simplify the code.
- In Cygwin restrict global cygheap locale info to the job performed
by internal_setlocale. Use UTF-8 instead of ASCII on the fly in
internal conversion functions.
- In Cygwin dll_entry, make sure to initialize a TLS area with a NULL
_REENT->_locale pointer. Add comment to explain why.
