Subject: Use a struct in_addr to insure alignment of address - instead of
X-Git-Tag: krb5-1.7-alpha1~37
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=b3a5ec5c59e2c854a9372e0b44bc50db4d755b84;p=krb5.git

Use a struct in_addr to insure alignment of address - instead of
random alignment on the stack. Solaris 2.10 has issues if the address
is not aligned.  The rest of the code in the tree uses a struct
in_addr or mallocs the address - which will be sufficiently aligned.

ticket: 6308
