(please Cc: your reply to jeff at cis.jhu.edu) hey :) I was trying to build 2.1 on AIX 4.3.3, and got an undefined symbol: ld: 0711-317 ERROR: Undefined symbol: .WCOREDUMP from wait(2): STANDARDS The wait() and waitpid() functions are defined by POSIX; wait4() and wait3() are not specified by POSIX. The WCOREDUMP() macro and the ability to restart a pending wait() call are extensions to the POSIX interface.
