Two compression questions

We have successful deployed a FIPS build of OpenSSL 0.9.7m w/zlib compression on Windows clients and linux servers in stunnel.  Now we want to upgrade to a FIPS build of 0.9.8k.  We are running into a couple of issues.  Here are my two questions:

1.       Should a 0.9.7m build work with a 0.9.8k build?  Mixing client and server versions seems to cause compression issues.  We get errors like: SSL3_GET_RECORD:bad decompression.  When I turn off zlib compression the two different versions work fine.

2.       Is the RLE compression truly implemented?  The c_rle.c file does not seem to have any RLE compression routines in it.

Thanks.
