36 # DES_RISC1     use different DES_ENCRYPT macro that helps reduce register
37 #               dependancies but needs to more registers, good for RISC CPU's
38 # DES_RISC2     A different RISC variant.
39 # DES_UNROLL    unroll the inner DES loop, sometimes helps, somtimes hinders.

51 # RC4_LONG      use 'long' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
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).
56 # MD5_ASM       use some extra md5 assember,

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

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