    1.30 + * \brief Basic types for the platform.
    1.31 + *
    1.32 + * This file used to be generated by autoconf/configure.
    1.33 + * Starting with ICU 49, platform.h is a normal source file,
    1.34 + * to simplify cross-compiling and working with non-autoconf/make build systems.
    1.35 + *
    1.36 + * When a value in this file does not work on a platform, then please
    1.37 + * try to derive it from the U_PLATFORM value
    1.38 + * (for which we might need a new value constant in rare cases)
    1.39 + * and/or from other macros that are predefined by the compiler
    1.40 + * or defined in standard (POSIX or platform or compiler) headers.
    1.41 + *
    1.42 + * As a temporary workaround, you can add an explicit <code>#define</code> for some macros
    1.43 + * before it is first tested, or add an equivalent -D macro definition
    1.44 + * to the compiler's command line.
    1.45 + *
    1.46 + * Note: Some compilers provide ways to show the predefined macros.
    1.47 + * For example, with gcc you can compile an empty .c file and have the compiler
    1.48 + * print the predefined macros with
    1.49 + * \code
    1.50 + * gcc -E -dM -x c /dev/null | sort
    1.51 + * \endcode
    1.52 + * (You can provide an actual empty .c file rather than /dev/null.
    1.53 + * <code>-x c++</code> is for C++.)
