26 # This becomes the value of INSTALLTOP in Makefile
27 # (Default: /usr/local)

38 # --cross-compile-prefix Add specified prefix to binutils components.
40 # --api One of 0.9.8, 1.0.0 or 1.1.0. Do not compile support for
41 # interfaces deprecated as of the specified OpenSSL version.

52 # no-asm do not use assembler
53 # no-dso do not compile in any native shared-library methods. This

55 # no-egd do not compile support for the entropy-gathering daemon APIs
56 # [no-]zlib [don't] compile support for zlib compression.

65 # DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
66 # provided to stack calls. Generates unique stack functions for

68 # DES_PTR use pointer lookup vs arrays in the DES in crypto/des/des_locl.h
69 # DES_RISC1 use different DES_ENCRYPT macro that helps reduce register
70 # dependancies but needs to more registers, good for RISC CPU's
71 # DES_RISC2 A different RISC variant.

84 # RC4_LONG use 'long' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
