 ticket: 6364
 subject: declare replacement [v]asprintf functions
 target_version: 1.7
 tags: pullup

 If HAVE_VASPRINTF is not defined, make sure krb5int_{,v}asprintf
 functions always get declared, applying the preprocessor conditional
 test only to the GCC format attribute.  If HAVE_VASPRINTF is defined,
 don't declare them at all.

 This fixes a bunch of function-not-declared warnings under Sun cc.
