56 * with the advent of *real* compilers for DOS, they are not locked together.
57 * MSDOS means "I am running on MSDOS". HAS_64K_LIMIT means "I have

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