Hi,
the following patch to cipher.c enables OpenSSH 3.9.1 to compile on IRIX 5.3
with the native IDO cc:

This is because OpenSSL does not define these function pointers as const, and
the IRIX 5.3 IDO cc is quite picky on such details and refuses to compile
otherwise.
The second patch is for the same reason. While not strictly necessary here, it
does away with some annoying warnings for the same reasons.

This issue might apply to other non-gcc compilers as well.
I'd appreciate your feedback.
