# DES_PTR	use pointer lookup vs arrays in the DES in crypto/des/des_locl.h
# DES_RISC1	use different DES_ENCRYPT macro that helps reduce register
#		dependancies but needs to more registers, good for RISC CPU's
# DES_RISC2	A different RISC variant.
# DES_UNROLL	unroll the inner DES loop, sometimes helps, somtimes hinders.
# DES_INT	use 'int' instead of 'long' for DES_LONG in crypto/des/des.h
#		This is used on the DEC Alpha where long is 8 bytes
#		and int is 4
# BN_LLONG	use the type 'long long' in crypto/bn/bn.h
# MD2_CHAR	use 'char' instead of 'int' for MD2_INT in crypto/md2/md2.h

#		array lookups instead of pointer use.
# RC4_CHUNK	enables code that handles data aligned at long (natural CPU
#		word) boundary.
# RC4_CHUNK_LL	enables code that handles data aligned at long long boundary
#		(intended for 64-bit CPUs running 32-bit OS).
# BF_PTR	use 'pointer arithmatic' for Blowfish (unsafe on Alpha).
# BF_PTR2	intel specific version (generic version is more efficient).
# MD5_ASM	use some extra md5 assember,

#### Unified HP-UX ANSI C configs.
# Special notes:
# - Originally we were optimizing at +O4 level. It should be noted
#   that the only difference between +O3 and +O4 is global inter-
#   procedural analysis. As it has to be performed during the link
#   stage the compiler leaves behind certain pseudo-code in lib*.a
#   which might be release or even patch level specific. Generating
#   the machine code for and analyzing the *whole* program appears
#   to be *extremely* memory demanding while the performance gain is
#   actually questionable. The situation is intensified by the default
#   HP-UX data set size limit (infamous 'maxdsiz' tunable) of 64MB
#   which is way too low for +O4. In other words, doesn't +O3 make
#   more sense?
# - Keep in mind that the HP compiler by default generates code
#   suitable for execution on the host you're currently compiling at.
#   If the toolkit is ment to be used on various PA-RISC processors
#   consider './config +Dportable'.
# - +DD64 is chosen in favour of +DA2.0W because it's ment to be
#   compatible with *future* releases.
# - If you run ./Configure hpux-parisc-[g]cc manually don't forget to
#   pass -D_REENTRANT on HP-UX 10 and later.
# - -DMD32_XARRAY triggers workaround for compiler bug we ran into in
#   32-bit message digests. (For the moment of this writing) HP C
#   doesn't seem to "digest" too many local variables (they make "him"
#   chew forever:-). For more details look-up MD32_XARRAY comment in
#   crypto/sha/sha_lcl.h.

# Cray T90 (SDSC)

# defined.  The T90 ints and longs are 8 bytes long, and apparently the
# B_ENDIAN code assumes 4 byte ints.  Fortunately, the non-B_ENDIAN and
# non L_ENDIAN code aligns the bytes in each word correctly.
#
# The BIT_FIELD_LIMITS define is to avoid two fatal compiler errors:
#'Taking the address of a bit field is not allowed. '
#'An expression with bit field exists as the operand of "sizeof" '

# The BIT_FIELD_LIMITS define was written for the C90 (it seems).  I added

# for some st_addr stuff, and then sizeof and address-of fails
# I could not use the ams/alpha.o option because the Cray assembler, 'cam'
