Robbins <arnold@skeeve.com> 210 211 * regdir/beebe.tar: Fix longwrds.ok so that the test will pass. 212 The file was incorrectly sorted. 213 2142018-06-06 Arnold D.

Robbins <arnold@skeeve.com> 238 239 Add POSIX-required formats %a and %A. 240 241 * run.c (format): Check for %a support in C library.

See 294 bugs-fixed/system-status.awk. 295 296 * run.c (bltin): For FSYSTEM, use the macros defined for wait(2) 297 to produce a reasonable exit value, instead of doing a floating-point 298 division by 256. 299 * awk.1: Document the return status values. 300 * bugs-fixed/README: Updated. 301 * bugs-fixed/system-status.awk, bugs-fixed/system-status.bad, 302 bugs-fixed/system-status.ok: New files. 303 3042018-05-22 Arnold D.
