... no it doesn't need a prototype, you already have a prototype. In
fact, the error below is probably intentional, to tell configure you
already have a prototype.

You do realize I hope that config.log doesn't record the results of
compiling the program, but is a series of tests used in order to
determine how to compile the application, and some failures are to be

This is a libc6 file, on my system, that line reads:

extern char *crypt (__const char *__key, __const char *__salt) __THROW;

So yes, I would guess, you definitely do have a prototype.

This crypt function on the other hand only takes one parameter, not two,
hence the conflict. Since that test program failed, configure knows that
the crypt function doesn't need or want another prototype.

Crypt is a primitive routine in the standard C library for creating
password entries in /etc/passwd.

You do not need openssl or libdes or anything else to provide crypt

I doubt if openssl or libdes even provide a crypt function.

I hope that this clears up some confusion which seems apparent in your
discussions with Johan.
