Newbie compilation problem: "parsdate.y: not found"

Hi, all -

I'm trying to compile tin 1.5.8 under cygwin, but when I run the
make command, I get the following:

===============================================================

me@machine ~/tin-1.5.8/src
$ make
gcc -DHAVE_CONFIG_H -I. -I../include -I../pcre -I../pcre -DLOCALEDI
R=\"/usr/local/share/locale\" -I../include    -O2  -c ./active.c
(snip lots of lines)
gcc -DHAVE_CONFIG_H -I. -I../include -I../pcre -I../pcre -DLOCALEDI
R=\"/usr/local/share/locale\" -I../include    -O2  -c ./page.c
expect 6 shift/reduce conflicts...
./parsdate.y
./parsdate.y: not found
make: *** [parsdate.o] Error 127

me@machine ~/tin-1.5.8/src
$ make
expect 6 shift/reduce conflicts...
./parsdate.y
./parsdate.y: not found
make: *** [parsdate.o] Error 127

me@machine ~/tin-1.5.8/src
$ ls par*.y
  25 parsdate.y

me@machine ~/tin-1.5.8/src
$ cat parsdate.y
%{

===============================================================

I am a novice to the whole cygwin environment, tin, and *nix (but
not command lines!) in general.  But I cannot understand why the
make command is claiming it cannot find the file which is clearly
present and valid in the src directory.

I saw another thread in this group that implied that one needs
something called 'yacc' to be installed, and I don't recall ever
installing it, but it doesn't look to me like it's even getting
that far.  Would the "parsdate.y: not found" error be appropriate
if, in fact, parsdate.y is present but the interpreter isn't?

Can anyone out there steer me in the right direction?  I know what
the makefile is and enough vi to edit it, but I haven't a clue what
to change.  What might I have done wrong?  (Remember, I'm a newbie,
so be gentle... :)
