Hi Dan, thanks for your answer!

Well, it's about my app's SSL library detection :) I need to know which
SSL library is used by libcurl to set the right crypto locking callbacks.
I used to test for the linker flags in my configure to determine the SSL
library used by libcurl.

The distributions (Kubuntu) curl-config gives me the following:
mike_at_honeybadger:~/cvs/curl$ /usr/bin/curl-config --libs
-L/usr/lib -lcurl -L/usr/lib -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lkrb5support -lresolv -lidn -lssl -lcrypto -ldl -lssl -lcrypto -lz
mike_at_honeybadger:~/cvs/curl$ /usr/bin/curl-config --feature
mike_at_honeybadger:~/cvs/curl$ /usr/bin/curl-config --version
So I wonder if I'm doing something wrong or I'm just missing some
curl configure flags, or do you think this flags are added by the
distributions libcurl package maintainer?
