It appears that curl 7.19.4 has now broken building against a local build
of OpenSSL. This worked fine with Curl 7.19.2.

The error I get while building against a custom local build of OpenSSL is:

In file included from /usr/include/openssl/ssl.h:179,
                 from urldata.h:63,
                 from file.c:75:
/usr/include/openssl/kssl.h:136: error: syntax error before "krb5_octet"

[snip]

Now, why in the world is it even *looking* at the /usr/include openssl
headers? I specifically passed in:

    --with-ssl=/opt/zimbra/openssl-0.9.8k

Which should be correct according to configure:

  --with-ssl=PATH Where to look for OpenSSL, PATH points to the SSL
                          installation (default: /usr/local/ssl); when
                          possible, set the PKG_CONFIG_PATH environment
                          variable instead of using this option

It seems like the logic in configure no longer matches the documented (and
previously working) description of --with-ssl.

./configure: line 23438: /opt/zimbra/openssl-0.9.8k: is a directory

which is, of course, exactly what it should be (a directory).

Line 23438 is:

    if "$PREFIX_OPENSSL" != "/usr" ; then

This IF statement did not exist in curl 7.19.2.

Changing the line to read:

if test "$PREFIX_OPENSSL" != "/usr" ; then

fixes the problem
