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

32 # given with --prefix.

38 # just as well use "make INSTALL_PREFIX=/whatever install".
40 # --cross-compile-prefix Add specified prefix to binutils components.
42 # --api One of 0.9.8, 1.0.0 or 1.1.0. Do not compile support for
43 # interfaces deprecated as of the specified OpenSSL version.

54 # no-asm do not use assembler
55 # no-dso do not compile in any native shared-library methods. This
56 # will ensure that all methods just return NULL.
57 # no-egd do not compile support for the entropy-gathering daemon APIs
58 # [no-]zlib [don't] compile support for zlib compression.
