Sounds good.

I have just fixed the reported bugs in 2.0 (from 2.0 to 2.0.1). If there 
are more bugs I will try to fix them in 2.0.x.

The perl module and C library are totally new. I am making all new 
aditions and modifications to this package:
- New index engine to handle document types
- Memory issues
- Thread safe search
- Sample perl module
- etc.
So all the effort is being made in this package. In fact, I have built 
swish-e exec on the top of the C library.
I think thish package should be swish-e-2.1 but it is quite 
experimental (alpha) now.

Both files are almost identical. I have just removed the word "static" 
in some lines to get a thread safe code. Since I have not made too 
much work on it you can use 2.0.1 file. I think that Dave is taking a 
look on it.
BTW, at least, to get a thread safe stemmer.c, it is important to 
remove the word static from the following line:

static char *end;

Do make test. If this works, the library is working OK (swish-e is 
built on top of the the library).

So the problem seems to be in the perl part. After installing (as 
root) it you should see something like (sorry for the broken lines)...

# make install
Skipping /usr/local/lib/perl5/site_perl/sun4-
solaris/./auto/SWISHE/ (unchanged)

(the Skipping is because it is already installed)

Do not worry about warnings while building testlib. If you get the 
exec file, it should be OK. Note that and testlib needs to 
access the test index file in ../tests/test.index  (make test is

Of course, but we need a thread safe function.
