1.1     ! root        1: This file contains a collection of notes that various people have

        !             6: for questions about porting Tcl to a particular machine;  in these

        !            40: end of the string.  Because of this, the history substitution loop

        !            65: 
        !            66: 1. The #define for TCL_UNION_WAIT in tclUnix.h needs to be set to 0,
        !            67: not 1.  I've tried a number of techniques to get the "config" script
        !            68: to figure this out and set it correctly, but so far I haven't been
        !            69: able to make it work for HP-UX systems.
        !            70: 
        !            71: 2. It may also be useful to add the flag "-D_BSD" to CFLAGS in the
        !            72: Makefile, but I'm not sure this is necessary (and it may even be
        !            73: evil) if TCL_UNION_WAIT has been #define'd correctly.

        !            88: 
        !            89: 1. The system version of strtoul is buggy, at least under some
        !            90: versions of AIX.  If the expression tests fail, try forcing Tcl
        !            91: to use its own version of strtoul instead of the system version.
        !            92: To do this, first copy strtoul.c from the compat subdirectory up
        !            93: to the main Tcl directory.  Then modify the Makefile so that
        !            94: the definition for COMPAT_OBJS includes "strtoul.o".  Note:  the
        !            95: "config" script should now detect the buggy strtoul and substitute
        !            96: Tcl's version automatically.
        !            97: 
        !            98: 2. You may have to comment out the declaration of open in tclUnix.h.
        !            99: 
        !           100: 3. The "nm -p ..." line in the file "config" has to be changed to
        !           101: "nm -en ..." if you use the version of nm that's in /bin.  If you're
        !           102: set up to use the BSD version (in /usr/ucb) then this won't be a
        !           103: problem.

        !           137: 
        !           138: 2. In tclUnix.h, add the following just before the declaration of environ:
