OpenSSL-fips-0_9_7-stable.
Since the 0.9.7-stable branch is supposed to be in freeze and should
only contain bug corrections, this change removes the FIPS changes
from that branch.
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.
I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.
