I had been always successful with Configure for last several releases. But with 1.0.2h, I am not able to run Configure correctly. Note that I am on Windows msys. Here is what I get : $ ./configure no-symlinks shared mingw Configuring for mingw ? ? no-ec_nistp_64_gcc_128 [default] ?OPENSSL_NO_EC_NISTP_64_GCC_128 (skip dir) ? ? no-gmp ? ? ? ? ?[default] ?OPENSSL_NO_GMP (skip dir) ? ? no-jpake ? ? ? ?[experimental] OPENSSL_NO_JPAKE (skip dir) ? ? no-krb5 ? ? ? ?
