/*
 * Try to keep one section per platform, compiler and architecture, otherwise,
 * if an existing section is reused for a different one and later on the
 * original is adjusted, probably the piggybacking one can be adversely
 * changed.
 *
 * In order to differentiate between platforms/compilers/architectures use
 * only compiler built-in predefined preprocessor symbols.
 *
 * curl_off_t
 * ----------
 *
 * For any given platform/compiler curl_off_t must be typedef'ed to a 64-bit
 * wide signed integral data type. The width of this data type must remain
 * constant and independent of any possible large file support settings.
 *
 * As an exception to the above, curl_off_t shall be typedef'ed to a 32-bit
 * wide signed integral data type if there is no 64-bit type.
 *
 * As a general rule, curl_off_t shall not be mapped to off_t. This rule shall
 * only be violated if off_t is the only 64-bit data type available and the
 * size of off_t is independent of large file support settings. Keep your
 * build on the safe side avoiding an off_t gating. If you have a 64-bit
 * off_t then take for sure that another 64-bit data type exists, dig deeper
 * and you will find it.
