Linux wilbur 2.2.12-20 #1 Mon Sep 27 10:40:35 EDT 1999 i686 unknown

>Description:
On compiling, I get this error message:

gcc -c -g -O2   -I../../../insight-5.0/tcl/unix/../generic -I../../../insight-5.0/tcl/unix -DHAVE_GETCWD=1 -DHAVE_OPENDIR=1 -DHAVE_STRSTR=1 -DHAVE_STRTOL=1 -DHAVE_TMPNAM=1 -DHAVE_WAITPID=1 -DNO_SYS_WAIT_H=1 -DHAVE_UNISTD_H=1 -DUSE_TERMIOS=1 -DHAVE_SYS_TIME_H=1 -DTIME_WITH_SYS_TIME=1 -DHAVE_TM_ZONE=1 -DHAVE_TM_GMTOFF=1 -DHAVE_TIMEZONE_VAR=1 -DHAVE_TIMEZONE_DECL=1 -DHAVE_ST_BLKSIZE=1 -DSTDC_HEADERS=1 -DNEED_MATHERR=1 -DRETSIGTYPE=void -DHAVE_SIGNED_CHAR=1 -DHAVE_SYS_IOCTL_H=1        -DTCL_SHLIB_EXT=\".so\" ../../../insight-5.0/tcl/unix/../generic/tclPipe.c
../../../insight-5.0/tcl/unix/../generic/tclPipe.c: In function `TclCleanupChildren':
../../../insight-5.0/tcl/unix/../generic/tclPipe.c:274: storage size of `waitStatus' isn't known

The problem is that WAIT_STATUS_TYPE was defined to be
`union wait', which was not defined.
>How-To-Repeat:
Compile out of the box on my system (RedHat 6.2).
>Fix:
  I fixed the problem by
putting `#include <sys/wait.h>' in 
.../insight-5.0/tcl/unix/tclUnixPort.h in this chunk of
code (lines 179-188):

#ifdef _AIX
#   define WAIT_STATUS_TYPE pid_t
#else
#ifndef NO_UNION_WAIT
#include <sys/wait.h>
#   define WAIT_STATUS_TYPE union wait
#else
#   define WAIT_STATUS_TYPE int
#endif
#endif
