[Haifux] amd64

[yakoub abaya]

i do not understand the difficulty for developers to release amd64
version of their software .

i don't have good understand of architecture from software point of view,
but i imagine the problem varies according to the type of the software .

so if low level library software are released in version amd64, what
is stopping application level like skype from being released as well ?

and from another point of view: how to write amd64 software ?
like if i write a simple standard C++ program and compile it using
amd64 then obviously it runs on that architecture .

so assume skype is written in C++, what is stopping them from simply
compiling it using an amd64 gcc ?
is it only a dependency problem, that skype depends on various
libraries that in turn don't have amd64 version ?
