Subject: Fix DES_LONG breakage
X-Git-Tag: OpenSSL_1_1_0-pre2~24
X-Git-Url: https://git.openssl.org/?p=openssl.git;a=commitdiff_plain;h=bdb1d0c24b3df3e2253cd8289cd619093524464e;hp=dbc8541b86aee7b6e13e2208545fe625fc13cd7b;ds=sidebyside

Fix DES_LONG breakage

For some strange reason opensslconf.h was only defining DES_LONG
when included via des.h, but that's exceedingly fragile (as a
result of include guards the include via des.h might not actually
process the content again).

Ripped out the nesting constraint, now always define OSSL_DES_LONG
if not already defined.  Note, this could just be DES_LONG, but
trying to avoid exposing DES_LONG in places where it has never been
seen before, so it is up to des.h to actually define DES_LONG as
OSSL_DES_LONG.
