156 * <rich@phekda.freeserve.co.uk>: The DJGPP port has code that converts
157 * the return code of system() into the form that Unixy wait usually
158 * returns:
159 *
160 * - signal number in bits 0-6;
161 * - core dump flag in bit 7;
162 * - exit code in bits 8-15.
163 *
164 * Bits 0-7 are always zero for DJGPP, because it uses system().
165 * See djgpp.c.
166 *
167 * POSIX::W* use the W* macros from <sys/wait.h> to decode
168 * the return code. Unfortunately the W* macros for DJGPP use
169 * a different format than Unixy wait does. So there's a mismatch
170 * and, say, WEXITSTATUS($?) will return bogus values.
171 *
172 * So here we add hack to redefine the W* macros from DJGPP's <sys/wait.h>
173 * to work with our return-code conversion.
