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

jpayne@69:  * We used to define one different, value-less macro per platform.
