38 # DES_RISC2     A different RISC variant.

52 # RC4_INDEX     define RC4_INDEX in crypto/rc4/rc4_locl.h.  This turns on
53 #               array lookups instead of pointer use.
54 # BF_PTR        use 'pointer arithmatic' for Blowfish (unsafe on Alpha).
55 # BF_PTR2       intel specific version (generic version is more efficient).

215 # Cray T90 (SDSC)
216 # It's Big-endian, but the algorithms work properly when B_ENDIAN is NOT
217 # defined.  The T90 ints and longs are 8 bytes long, and apparently the
218 # B_ENDIAN code assumes 4 byte ints.  Fortunately, the non-B_ENDIAN and
219 # non L_ENDIAN code aligns the bytes in each word correctly.
220 #
221 # The BIT_FIELD_LIMITS define is to avoid two fatal compiler errors:
222 #'Taking the address of a bit field is not allowed. '
223 #'An expression with bit field exists as the operand of "sizeof" '

232 # for some st_addr stuff, and then sizeof and address-of fails

709 NOTE: The OpenSSL header files have been moved from include/*.h
710 to include/openssl/*.h.  To include OpenSSL header files, now
711 directives of the form
712      #include <openssl/foo.h>
713 should be used instead of #include <foo.h>.
714 These new file locations allow installing the OpenSSL header
715 files in /usr/local/include/openssl/ and should help avoid
716 conflicts with other libraries.
717
718 To compile programs that use the old form <foo.h>,
719 usually an additional compiler option will suffice: E.g., add
720      -I$prefix/include/openssl
721 or
722      -I$pwd/include/openssl
723 to the CFLAGS in the Makefile of the program that you want to compile
724 (and leave all the original -I...'s in place!).
725
726 Please make sure that no old OpenSSL header files are around:
727 The include directory should now be empty except for the openssl
728 subdirectory.
