/*
* Since <krb5/common_plugin.h> is new with Heimdal 8, users looking to write
* portable plugins across Heimdal 7 and 8 need a conditional compilation
* predicate from a header file that does exist in both major releases. This
* is as good a place as any to define a plugin source-compatibility version
* number.
*
* When this macro is defined and is equal to 1, the Heimdal 8 plugin source
* API, and <krb5/common_plugin.h> header are available and should be used.
*
* In Heimdal 7, this macro is not defined, and <krb5/common_plugin.h> may not
* be available.
