jpayne@69 28 * \file
jpayne@69 29 * \brief Basic types for the platform.
jpayne@69 30 *
jpayne@69 31 * This file used to be generated by autoconf/configure.
jpayne@69 32 * Starting with ICU 49, platform.h is a normal source file,
jpayne@69 33 * to simplify cross-compiling and working with non-autoconf/make build systems.
jpayne@69 34 *
jpayne@69 35 * When a value in this file does not work on a platform, then please
jpayne@69 36 * try to derive it from the U_PLATFORM value
jpayne@69 37 * (for which we might need a new value constant in rare cases)
jpayne@69 38 * and/or from other macros that are predefined by the compiler
jpayne@69 39 * or defined in standard (POSIX or platform or compiler) headers.
jpayne@69 40 *
jpayne@69 41 * As a temporary workaround, you can add an explicit \#define for some macros
jpayne@69 42 * before it is first tested, or add an equivalent -D macro definition
jpayne@69 43 * to the compiler's command line.
jpayne@69 44 *
jpayne@69 45 * Note: Some compilers provide ways to show the predefined macros.
jpayne@69 46 * For example, with gcc you can compile an empty .c file and have the compiler
jpayne@69 47 * print the predefined macros with
jpayne@69 48 * \code
jpayne@69 49 * gcc -E -dM -x c /dev/null | sort
jpayne@69 50 * \endcode
jpayne@69 51 * (You can provide an actual empty .c file rather than /dev/null.
jpayne@69 52 * <code>-x c++</code> is for C++.)

jpayne@69 70 * The U_PLATFORM macro defines the platform we're on.
jpayne@69 71 *
jpayne@69 72 * We used to define one different, value-less macro per platform.
jpayne@69 73 * That made it hard to know the set of relevant platforms and macros,
jpayne@69 74 * and hard to deal with variants of platforms.
jpayne@69 75 *
jpayne@69 76 * Starting with ICU 49, we define platforms as numeric macros,
jpayne@69 77 * with ranges of values for related platforms and their variants.
jpayne@69 78 * The U_PLATFORM macro is set to one of these values.
jpayne@69 79 *
jpayne@69 80 * Historical note from the Solaris Wikipedia article:
jpayne@69 81 * AT&T and Sun collaborated on a project to merge the most popular Unix variants
jpayne@69 82 * on the market at that time: BSD, System V, and Xenix.
jpayne@69 83 * This became Unix System V Release 4 (SVR4).
