Missing tree-check.h when building gcc 2000-12-17 cvs snapshot on win2k/pro with cygwin

[Christian Jönsson <chj at lin dot foa dot se>]

I tried compiling the gcc cvs sources 2000-12-17 (about 20:41 + 01:00)
on my win2k/pro box using a cygwin 1.1.7s(0.31/3/2) 2000-12-13 23:55
snapshot. I also applied the getopt patch suggested in
http://gcc.gnu.org/ml/gcc-patches/2000-11/msg00908.html

Here's where it got me:

gcc -c  -DIN_GCC    -g  -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long
 -DHAVE_CONFIG_H -DGENERATOR_FILE    -I. -I. -I../../gcc/gcc
-I../../gcc/gcc/. -I../../gcc/gcc/config -I../../gcc/gcc/../include \

Any ideas?
