Well, a bit, since there would be TCL_CFLAGS and TCL_LIBS, but a
TK_LIBS without a corresponding TK_CFLAGS, unless it were either empty
or contained just the flag for the required X includes, and I'm not
sure what there would be for itcl.  Come to think of it, perhaps a null
TK_CFLAGS wouldn't be a problem.  Perhaps that's best.  OK, I'll do
that.

I've just found an itkConfig.sh in the itcl build tree, which is
configured (from .in) but not installed, and after grepping around the
rest of my system for *Config.sh, I've found an itclConfig.sh.in which
isn't even configured, much less installed.  Is something terribly
broken with the itcl distribution we have?

Programming in oodles of portable-sh has lost its minimalist charm.
