137  *
138  * - signal number in bits 0-6;
139  * - core dump flag in bit 7;
140  * - exit code in bits 8-15.

146  * the return code. Unfortunately the W* macros for DJGPP use
147  * a different format than Unixy wait does. So there's a mismatch
148  * and, say, WEXITSTATUS($?) will return bogus values.

151  * to work with our return-code conversion.
