"-fips" would indeed have been reported if I had included OpenSSL
headers in a specific order.  Namely,
  #include <openssl/opensslconf.h>
needs to be before:
  #include <openssl/opensslv.h>
.  I will correct this issue in the next release of stunnel.

Yes, it is.  It just does not report it properly.

"fips = yes" option only works when OpenSSL is built with FIPS canister.
It is "compliant" when built according to the FIPS Security Policy:
http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf
, where building with FIPS canister is the most basic requirement.

Thank you very much for reporting this issue!
