152 | * <rich@phekda.freeserve.co.uk>: The DJGPP port has code that converts | |
153 | * the return code of system() into the form that Unixy wait usually | |
154 | * returns: | |
155 | * | |
156 | * - signal number in bits 0-6; | |
157 | * - core dump flag in bit 7; | |
158 | * - exit code in bits 8-15. | |
159 | * | |
160 | * Bits 0-7 are always zero for DJGPP, because it uses system(). | |
161 | * See djgpp.c. | |
162 | * | |
163 | * POSIX::W* use the W* macros from <sys/wait.h> to decode | |
164 | * the return code. Unfortunately the W* macros for DJGPP use | |
165 | * a different format than Unixy wait does. So there's a mismatch | |
166 | * and, say, WEXITSTATUS($?) will return bogus values. | |
167 | * | |
168 | * So here we add hack to redefine the W* macros from DJGPP's <sys/wait.h> | |
169 | * to work with our return-code conversion. | |
