You could also just look at the '# line' lines, e.g.,
'# 159 "/usr/include/tcl.h" 3 4'

The most interesting thing is whether Tcl_CreateCommand is declared, and
whether its signature corresponds to its usage in ext.c.

Ha.  /cygdrive is a virtual directory, intended to access Windows disks
from inside Cygwin, not vice versa.  Why go to C:/cygwin/cygdrive/c/, when
you can simply go to C:/?

Both of the above seem to indicate that the Tcl library you're using is
probably a Windows native Tcl of some sort...  I may be totally off,
though, since I don't know squat about Tcl.
