KWIML: The Kitware Information Macro Library 

Provides header files that use preprocessor tests to detect and provide
information about the compiler and its target architecture.  The headers
contain no configuration-time test results and thus may be installed
into an architecture-independent include directory.  This makes them
suitable for use in the public interface of any package.

/*
This header defines macros with information about the C ABI.
Only information that can be determined using the preprocessor at
compilation time is available. No try-compile results may be added
here. Instead we memorize results on platforms of interest.
An includer may optionally define the following macros to suppress errors:
@KWIML@_ABI_NO_VERIFY = skip verification declarations
@KWIML@_ABI_NO_ERROR_CHAR_SIGN = signedness of 'char' may be unknown
@KWIML@_ABI_NO_ERROR_LONG_LONG = existence of 'long long' may be unknown
@KWIML@_ABI_NO_ERROR_ENDIAN = byte order of CPU may be unknown
An includer may test the following macros after inclusion:
@KWIML@_ABI_SIZEOF_DATA_PTR = sizeof(void*)
@KWIML@_ABI_SIZEOF_CODE_PTR = sizeof(void(*)(void))
@KWIML@_ABI_SIZEOF_FLOAT = sizeof(float)
@KWIML@_ABI_SIZEOF_DOUBLE = sizeof(double)
@KWIML@_ABI_SIZEOF_CHAR = sizeof(char)
@KWIML@_ABI_SIZEOF_SHORT = sizeof(short)
@KWIML@_ABI_SIZEOF_INT = sizeof(int)
@KWIML@_ABI_SIZEOF_LONG = sizeof(long)
@KWIML@_ABI_SIZEOF_LONG_LONG = sizeof(long long) or 0 if not a type
Undefined if existence is unknown and error suppression macro
@KWIML@_ABI_NO_ERROR_LONG_LONG was defined.
@KWIML@_ABI_SIZEOF___INT64 = 8 if '__int64' exists or 0 if not
Undefined if existence is unknown.
@KWIML@_ABI___INT64_IS_LONG = 1 if '__int64' is 'long' (same type)
Undefined otherwise.
@KWIML@_ABI___INT64_IS_LONG_LONG = 1 if '__int64' is 'long long' (same type)
Undefined otherwise.
@KWIML@_ABI___INT64_IS_UNIQUE = 1 if '__int64' is a distinct type
Undefined otherwise.
@KWIML@_ABI_CHAR_IS_UNSIGNED = 1 if 'char' is unsigned, else undefined
@KWIML@_ABI_CHAR_IS_SIGNED = 1 if 'char' is signed, else undefined
One of these is defined unless signedness of 'char' is unknown and
error suppression macro @KWIML@_ABI_NO_ERROR_CHAR_SIGN was defined.
@KWIML@_ABI_ENDIAN_ID_BIG = id for big-endian (always defined)
@KWIML@_ABI_ENDIAN_ID_LITTLE = id for little-endian (always defined)
@KWIML@_ABI_ENDIAN_ID = id of byte order of target CPU
Defined to @KWIML@_ABI_ENDIAN_ID_BIG or @KWIML@_ABI_ENDIAN_ID_LITTLE
unless byte order is unknown and error suppression macro
@KWIML@_ABI_NO_ERROR_ENDIAN was defined.
We verify most results using dummy "extern" declarations that are
invalid if the macros are wrong. Verification is disabled if
suppression macro @KWIML@_ABI_NO_VERIFY was defined.

KWIML - The Kitware Information Macro Library
KWIML provides header files that use preprocessor tests to detect and
provide information about the compiler and its target architecture. The
headers contain no configuration-time test results and thus may be
installed into an architecture-independent include directory. This
makes them suitable for use in the public interface of any package.
This source tree is intended for distribution inside the source trees of
other packages. In order to avoid name collisions among multiple
packages the KWIML headers are configured with a per-package prefix on
both the header locations and the macros they define. See comments in
CMakeLists.txt for instructions to include KWIML inside another project.
The entire KWIML source tree is distributed under the OSI-approved
3-clause BSD License. Files used only for build and test purposes
contain a copyright notice and reference Copyright.txt for details.
Headers meant for installation and distribution outside the source tree
come with full inlined copies of the copyright notice and license text.
This makes them suitable for distribution with any package under
compatible license terms.
The following components are provided. See header comments for details:
ABI.h = Fundamental type size and representation
INT.h = Fixed-size integer types and format specifiers
The "test" subdirectory builds tests that verify correctness of the
information provided by each header.
