more configure options explained

       ./configure --disable-shared

     To tell the configure script to skip searching for thread-safe functions,

     add an option like:

       ./configure --disable-thread

     To build curl with kerberos4 support enabled, curl requires the krb4 libs

     and headers installed. You can then use a set of options to tell

     configure where those are:

          --with-krb4-includes[=DIR]   Specify location of kerberos4 headers

          --with-krb4-libs[=DIR]       Specify location of kerberos4 libs

          --with-krb4[=DIR]            where to look for Kerberos4

     In most cases, /usr/athena is the install prefix and then it works with

       ./configure --with-krb4=/usr/athena
