I already have tcl 8.4 installed from the cygwin packages.  I tried to 
tweak the makefile to show the different version information and even 
without any version info and it still doesn't work.

now when I run make I get several errors similar to :

gpsmanshp.o(.txt+0x2b69):gpsmanshp.c: undefined reference to 'Tcl_CreateObjcom
mand'

using these modifications to the makefile:

TCLVERSION = 84

INSTALLDIR = /usr/lib/tcl$(TCLVERSION)

CFLAGS = -Wall -fPIC -c -I/usr/include/tcl
LINKOPT = -lshp -ltcl$(TCLVERSION)

A quick scan of the various cygwin mailing lists shows several programs 
have some sort of trouble with "-ltcl" when compiling but I couldn't find 
any details of what was changed to make it work.

I'm not very clear on what is going on while it's compiling... hopefully 
someone understands it better than I.
