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

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
