/*64bit cpu notes:
string_t is a 32bit quantity.
this datatype needs to have enough bits to express any address that contains a string.
in a 32bit build, this is fine. with a qvm, the offset between the vm base and the string is always less than 32bits so this is fine too.
HOWEVER...
native code uses a base address of 0. this needs a 48bit datatype for any userland address. 32 bits just ain't enough.
even worse: ktx defines string_t as a 'char*'. okay, its 64bit at last... but it means that the entire entity field structure is now the wrong size with the wrong offsets.
this means CRASH!
how to fix? good luck with that. seriously.
the only sane way to fix it is to either define a better base address (say the dll base,
and require that all string_t values are bss or data and not from malloc, which is problematic when loading dynamic stuff from a map)
alternatively, you could create some string_t->pointer lookup. messy.
either way, string_t cannot be a pointer.
probably the best solution is to stop using string_t stuff completely. move all those string values somewhere else.
netnames will still mess things up.
so just use qvms.
oh, wait, ktx no longer supports those properly.
