# Usage: Configure [-Dxxx] [-Lxxx] [-fxxx] [-Kxxx] [no-asm] [rsaref]
#         [386] platform[:flags]
#
# Options:
# rsaref        use RSAref
# no-asm        do not use assembler
# 386           generate 80386 code
# -D, -L, -l, -f, -K: compiler options are passed through 
# 
# -DRSAref	build to use RSAref
# -DNO_IDEA	build with no IDEA algorithm
# -DNO_RC4	build with no RC4 algorithm
# -DNO_RC2	build with no RC2 algorithm
# -DNO_BF	build with no Blowfish algorithm
# -DNO_DES	build with no DES/3DES algorithm
# -DNO_MD2	build with no MD2 algorithm
#
# 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
# MD2_LONG	use 'long' instead of 'int' for MD2_INT in crypto/md2/md2.h
# IDEA_SHORT	use 'short' instead of 'int' for IDEA_INT in crypto/idea/idea.h
# IDEA_LONG	use 'long' instead of 'int' for IDEA_INT in crypto/idea/idea.h
# RC2_SHORT	use 'short' instead of 'int' for RC2_INT in crypto/rc2/rc2.h
# RC2_LONG	use 'long' instead of 'int' for RC2_INT in crypto/rc2/rc2.h
# RC4_CHAR	use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
# RC4_LONG	use 'long' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
# RC4_INDEX	define RC4_INDEX in crypto/rc4/rc4_locl.h.  This turns on
#		array lookups instead of pointer use.
# BF_PTR	use 'pointer arithmatic' for Blowfish (unsafe on Alpha).
# BF_PTR2	use a pentium/intel specific version.
# MD5_ASM	use some extra md5 assember,
# SHA1_ASM	use some extra sha1 assember, must define L_ENDIAN for x86
# RMD160_ASM	use some extra ripemd160 assember,

# 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'
