Absent any 'symbol map' or script to limit what gets exported, static linking of libraries previously resulted in a libcurl with curl's and those other symbols being (re-)exported. This did not happen if 'versioned symbols' were enabled (which is not the default) because then a version script is employed. This limits exports to everything starting in 'curl_*'., which is what "libcurl.vers" exports. This avoids strange side-effects such as with mixing methods from system libraries and those erroneously offered by libcurl.

Static-Linking dependencies to curl I noticed that curl re-exports those other symbols, which is unexpected.
