[Vala] Conditional vapis

[pancake <pancake youterm com>]

Talking about conditional vapis...

what do you think about including io.h and windows.h instead of unistd.h 
on posix.vapi
when including this file on windows? I understand that this should be a 
check to be
done in C and not at vala level because the generated C files should 
compile on linux
as well as on windows.

The problem I'm facing here is that GIO doesnt implement g_read g_write, 
... because it
relays on system's POSIX functions..which is weird. I opened a bug about 
it. but looks
like glib developers doesnt wants to add few #defines to fix that issue.

So, if I do something in vala that uses posix, the generated code is 
directly unusable
on Windows. which solution do you propose?

I dont see a clean/simple solution.. but i'm opened to ideas :)
