Alex Richardson f7c6a06cb7 Support architectures where long is smaller than pointers. 
I am currently trying to compile FreeType for CHERI-extended ISAs
(CHERI-RISC-V and Arm's Morello), but I am getting compiler warnings
from the `FT_UINT_TO_POINTER` macro.  When compiling with the CHERI
Clang compiler, not using `uinptr_t` for casts between integers an
pointers results in the following `-Werror` build failures:

```
In file included from .../src/truetype/truetype.c:22:
  .../src/truetype/ttgload.c:1925:22: error:
    cast from provenance-free integer type to pointer type will
    give pointer that can not be dereferenced
    [-Werror,-Wcheri-capability-misuse]
  node->data = FT_UINT_TO_POINTER( glyph_index );
               ^
  .../include/freetype/internal/compiler-macros.h:79:34: note:
    expanded from macro 'FT_UINT_TO_POINTER'
```

* include/freetype/internal/compiler-macros.h (FT_UINT_TO_POINTER):
The ISO C standard compliant fix for this would be to use
`uintptr_t` from `stdint.h`, but I am not sure if this is supported
by the minimum compiler version.  Therefore, use the
compiler-defined `__UINTPTR_TYPE__` macro (supported in GCC 4.6+ and
Clang since about 3.0) before checking for `_WIN64` and falling back
to `unsigned long`.

README 

FreeType 2.10.4
===============

Homepage: https://www.freetype.org

FreeType is a freely available software library to render fonts.

It  is  written  in  C,   designed  to  be  small,  efficient,  highly
customizable,  and portable  while capable  of producing  high-quality
output (glyph images) of most vector and bitmap font formats.

Please   read  the   `docs/CHANGES`   file,   it  contains   IMPORTANT
INFORMATION.

Read the files `docs/INSTALL*`  for installation instructions; see the
file `docs/LICENSE.TXT` for the available licenses.

For using FreeType's git repository  instead of a distribution bundle,
please read file `README.git`.

The FreeType 2 API reference is located in directory `docs/reference`;
use the file  `index.html` as the top entry point.   [Please note that
currently  the search  function  for  locally installed  documentation
doesn't work due to cross-site scripting issues.]

Additional documentation is  available as a separate  package from our
sites.  Go to

  https://download.savannah.gnu.org/releases/freetype/

and download one of the following files.

  freetype-doc-2.10.4.tar.xz
  freetype-doc-2.10.4.tar.gz
  ftdoc2104.zip

To view the documentation online, go to

Mailing Lists
-------------

The preferred  way of  communication with the  FreeType team  is using
e-mail lists.

  general use and discussion:      freetype@nongnu.org
  engine internals, porting, etc.: freetype-devel@nongnu.org
  announcements:                   freetype-announce@nongnu.org
  git repository tracker:          freetype-commit@nongnu.org

The lists are moderated; see

  https://www.freetype.org/contact.html

how to subscribe.


Bugs
----

Please submit bug reports at

  https://gitlab.freedesktop.org/freetype/freetype/-/issues

Alternatively,    you    might    report    bugs    by    e-mail    to
`freetype-devel@nongnu.org`.    Don't  forget   to  send   a  detailed
explanation of the problem -- there  is nothing worse than receiving a
terse message that only says 'it doesn't work'.


Patches
-------

For larger changes please provide merge requests at

  https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests

Alternatively, you can send patches to the `freetype-devel@nongnu.org`
mailing list  -- and thank you  in advance for your  work on improving
FreeType!

Details on the process can be found here:

Enjoy!
