 /**

  * \file

  * \brief Basic types for the platform.

  *

  * This file used to be generated by autoconf/configure.

  * Starting with ICU 49, platform.h is a normal source file,

  * to simplify cross-compiling and working with non-autoconf/make build systems.

  *

  * When a value in this file does not work on a platform, then please

  * try to derive it from the U_PLATFORM value

  * (for which we might need a new value constant in rare cases)

  * and/or from other macros that are predefined by the compiler

  * or defined in standard (POSIX or platform or compiler) headers.

  *

  * As a temporary workaround, you can add an explicit <code>#define</code> for some macros

  * before it is first tested, or add an equivalent -D macro definition

  * to the compiler's command line.

  *

  * Note: Some compilers provide ways to show the predefined macros.

  * For example, with gcc you can compile an empty .c file and have the compiler

  * print the predefined macros with

  * \code

  * gcc -E -dM -x c /dev/null | sort

  * \endcode

  * (You can provide an actual empty .c file rather than /dev/null.

  * <code>-x c++</code> is for C++.)

  * \def U_PLATFORM

  * The U_PLATFORM macro defines the platform we're on.

  *

  * We used to define one different, value-less macro per platform.

  * That made it hard to know the set of relevant platforms and macros,

  * and hard to deal with variants of platforms.

  *

  * Starting with ICU 49, we define platforms as numeric macros,

  * with ranges of values for related platforms and their variants.

  * The U_PLATFORM macro is set to one of these values.

  *

  * Historical note from the Solaris Wikipedia article:

  * AT&T and Sun collaborated on a project to merge the most popular Unix variants

  * on the market at that time: BSD, System V, and Xenix.

  * This became Unix System V Release 4 (SVR4).
