The tcltk-grass is completely different to Cygwin's Tcl/Tk. Cygwin's
version doesn't use X, and uses Windows pathnames rather than Cygwin
pathnames (presumably so that you can cut+paste filenames). The result
is that programs compiled for Cygwin's Tcl/Tk (AFAICT, this means gdb)
will only work with that version.

The two versions shouldn't conflict; tcltk-grass goes into /usr/local,
and contains static libraries, whereas Cygwin's version has DLLs.

[GRASS binaries which are linked against Tcl/Tk (e.g. NVIZ and
v.digit) still need the package for the /usr/local/lib/{tcl,tk}8.4
directories, while gis.m needs wish.]

It doesn't matter. Cygwin's setup program allows you to choose a
specific version (e.g. in case the latest version doesn't work).
