I tried current cvs and saw same problem. So, I tried the
patch and I could compile without problems(the HAVE_CHFLAGS
is not defined). Tested on Tru64Unix 5.1A against current
cvs(20030624).

I cannot find using grep under /usr/include "chflags" at all.
Although, I don't have any manpage chflags. Tru64Unix 5.1A

yes, the chflags() code is mine.

indeed also testing #ifdef UF_IMMUTABLE should workaround the 
issue, c.f. attached patch (could you test?)

however, if the chflags() API on these non-BSD OSs has similar 
functionality to the BSD one, we should try to use it if possible (it 
may only be a matter of adding an include do define UF_IMMUTABLE).
Could somebody provide manpages for chflags(2) on these systems? 
googling for "chflags Tru64" doesn't seem to yield anything 
interesting...
for reference, the BSD chflags(2) manpage:
    http://www.rocketaware.com/man/man2/chflags.2.htm

So this means that configure needs to test not only whether
there is a chflags() but whether it works.  Can't do that
myself (wrong version of autoconf and no experience with the
chflags() call either) but shouldn't be too challenging.

Assigning to Dan Steffen who I believe was the originator of
the chflags() code in Tcl.  Perhaps test for the define
UF_IMMUTABLE as well?

Oh, and a local workaround:

After running ./configure, just edit 'config.status', and find the -DHAVE_CHFLAGS. Delete it, save it, run './config.status', and then 'make'.  At least for me, the resulting binary passes 'make test' (more or less - I hit 3 unrelated errors that I need to look into).

Further debugging indicates that on Linux, this is a squirrely glibc issue - they've apparently added a dummy chflags() function, so autoconf tests for it find it, and hilarity ensues.

I've opened a RedHat bugzilla entry on this:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=97169

I also checked one of our Tru64 v5.1a boxes, and there is indeed a function chflags() in their libc.a
as well, so apparently there is a similar autoconf issue on Tru64.  I'm not enough of an autoconf wizard to suggest a resolution.

Isn't this related to OSX support (TIP#118)?

Sorry, not my area of expertise at all.
