Missing file while building Guththila's tests

While trying to build Guththila's tests I get the following error

~/axis-trunk/guththila/tests$ ./s

compiling reader tests
test.c:18: fatal error: check.h: No such file or directory

It seems that the file check.h is missing, I looked all over the repo and couldn't find it... Seems that Nandika was the one to upload the tests, perhaps that file is missing?

IMHO It would be useful to have guththila's tests running in order to avoid errors while fixing the code...
