This probably explains the problem I had when briefly trying to get
krb5-1.5-signed.tar working on OpenBSD.  There is no "dl" library on
OpenBSD, dlopen is in libc.  And sure enough, the generated file:

krb5-1.5/src/include

contains:

/* Define if dlopen should be used */
/* #undef USE_DLOPEN */

As a Quick'N'Dirty fix, can I just alter the above to:

#define USE_DLOPEN 1

after the configuration and just before the build?
