/**
|

* \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 #define 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++.)

/**

|

* 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,

|
||
* 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).
