| * \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++.) |
