Summary: gmake genstubs fail for tcl cvs head

Initial Comment:
platform sparc solaris 8 sun c compiler, tcl cvs head from tcl-20100208.tar.gz downloaded from activestate.

After configure, I ran gmake genstubs and got:
Emitting tclTomMath
syntax error in expression "$name in $hooks($intf)": extra tokens at end of expr
ession
    ("if" test expression)
    while compiling
"if {$name in $hooks($intf)} {
                set root 0
                break;
            }"
    ("if" then script line 2)
    while compiling
"if {[info exists hooks($intf)]} {
            if {$name in $hooks($intf)} {
                set root 0
                break;
            }
        }"
    ("foreach" body line 2)
    while compiling
"foreach intf [array names interfaces] {
        if {[info exists hooks($intf)]} {

                break;
            }

Message:
The tclsh in my path is a tclsh 8.4.9 version. genStubs.tcl has a package
require Tcl 8.4 in it. So the tclsh was seen as compatible by Tcl. Tcl then
declared the syntax wrong.

The tclsh executable is no longer created by the core build scripts. It
seems, to me, that the best solution would be for the core Makefiles to use
the tclsh naming conventions that it creates. Certainly people could come
along and create by hand additional links, etc. but the build environment
shouldn't depend on those being present.

Message:
Cannot repro on my Fedora 12 (bug GNU make also).

Note that this step (genstubs) depends on a previously installed tclsh.
Possibly in your case that's the system default tclsh, that can be a bit
old and not support the "in" infix operator in expressions.

 I hurry to add that if that's the case, then indeed it is a bug, because
the build system should take steps to be bootstrappable on reasonably old
Tcl version. Using too new constructs like "in" that are easy to emulate is
a mistake.
