* Why does compiler fail to compile sha512.c?
OpenSSL SHA-512 implementation depends on compiler support for 64-bit
integer type. Few elder compilers [ULTRIX cc, SCO compiler to mention a
couple] lack support for this and therefore are incapable of compiling
the module in question. The recommendation is to disable SHA-512 by
adding no-sha512 to ./config [or ./Configure] command line. Another
possible alternative might be to switch to GCC.
