If the last component of $inc_dir is 'openssl', set $inc_dir to its parent and set $prefix to 'openssl'. Otherwise, leave $inc_dir as is and set $prefix to '' (I hope this fixes bugs #28431, #28680, #32084, #43084, #54103 without breaking anything).
Improved OpenSSL detection on Win32/Strawberry Perl (bug #49285).
Add MIME::Base64 as a prerequisite as Net::SSL needs it.
exit 0 if OpenSSL can't be found to avoid superfluous reports from CPAN Testers.
Add \ to $opt_bench in eg/net-ssl-test (bugs #30931, #39363).
Changes for version 0.57_02 - 2010-08-08
Refactor the version detection algorithm in Makefile.PL to handle all known variations of version number encoding. Should fix bug #52408.
Changes for version 0.57_01 - 2008-02-18
use #include <..> rather than #include "..." in crypt_ssleay_version.h.
add command-line switch to avoid live tests (bug #30268).
skip tests in t/01-connect.t if 443 is already in use (bug #30985).
make code gcc -Wwrite-strings compatible (bug #31926).
