154 * <rich@phekda.freeserve.co.uk>: The DJGPP port has code that converts
155 * the return code of system() into the form that Unixy wait usually
156 * returns:
157 *
158 * - signal number in bits 0-6;
159 * - core dump flag in bit 7;
160 * - exit code in bits 8-15.
161 *
162 * Bits 0-7 are always zero for DJGPP, because it uses system().
163 * See djgpp.c.

165 * POSIX::W* use the W* macros from <sys/wait.h> to decode
166 * the return code. Unfortunately the W* macros for DJGPP use
167 * a different format than Unixy wait does. So there's a mismatch
168 * and, say, WEXITSTATUS($?) will return bogus values.
169 *
170 * So here we add hack to redefine the W* macros from DJGPP's <sys/wait.h>
171 * to work with our return-code conversion.
