The simplest fix may be -Dconst=
My gethostbyname() (netbsd) is declared like this:
struct hostent *gethostbyname __P((const char *));
If Unicos doesn't modify it's arg, the best fix may be to fix your
system header files not to imply that it does. If Unicos does modify
it's arg, you've got bigger problems....
I don't think gethostbyname() is defined by any standard, so there's
not really anything to hit Cray^H^H^H^HSGI over the head with.
