Re: Problems building TCL for insight on cygwin & win2k

Keith,

    I have now re-configed into an empty directory and re-built without
the -mwin32 flags. I now get the errors shown below:

make[3]: *** [tclPipe.o] Error 1

This is the problem I started with before adding the win32 flags. The
problem is that the lines use a set of macros defined in tclunixport.h that
assume that the value passed is an int, but the value passed isn't an int.
Here is the snippet of code fromthe .h file:


#ifdef _AIX
#   define WAIT_STATUS_TYPE pid_t
#else
#ifndef NO_UNION_WAIT
#   define WAIT_STATUS_TYPE union wait
#else
#   define WAIT_STATUS_TYPE int
#endif
#endif

/*
 * Supply definitions for macros to query wait status, if not already
 * defined in header files above.
 */

#ifndef WIFEXITED
#   define WIFEXITED(stat)  (((*((int *) &(stat))) & 0xff) == 0)
#endif

The value passed in the line that give erros in tclpipe.c use this WIFEXIT
but the value passed is of type WAIT_STATUS_TYPE and I guesss is of type
union wait rather than the int. So should there be a definition for
NO_UNION_WAIT or should the defines be within the #ifndef NO_UNION_WAIT so
they take account of the differeing types.
