Sorry I didn't make it clear earlier.
It results to the same warning when I compile libcurl. Looks like this:

libtool: link: gcc -g0 -O2 -Wno-system-headers -static -o curl main.o

And when I programming above curl, I link libcurl.a only without link
libssl.a . It comes to error like this:

I check libcurl.a, and find this:
[root_at_localhost curl-7.21.3]# nm -A ./lib/.libs/libcurl.a | grep SSL_write
./lib/.libs/libcurl.a:ssluse.o: U SSL_write

So, if libcurl.a is completely static, it shouldn't depend on openssl, and
SSL_write won't be undefined symbol in libcurl. Am I right?
