Subject: Use the actually correct define for solaris and gcc
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=26c57423933cab9e5aef6a30cb08c68528ac21b6;p=thirdparty%2Fopenssl.git

Use the actually correct define for solaris and gcc

And to avoid future confusion just namespace all of these
to OSSL_
