Just learning D, working with GLFW and dmd 1.030 on WinXP. The files glfw.d,
gl.d and glu.d shipped with the GLFW distribution contain the following...
version (Win32) {
extern (Windows):
}
version (linux) {
extern (C):
}
...which results in Symbol Undefined errors.
One of the files contains a variation...
version(Win32)
extern(Windows):
else
extern(C):
...which results in a syntax error on the 'else'.
I have tried all the variations I can think of, such as
version(Win32)
{
extern(Windows):
}
else
{
extern(C):
}
which also results in Symbol Undefined errors.
The only thing that works is...
version(Win32):
...on it's own. So I'm confused and would really appreciate it if anyone can
explain this behaviour.

Behaviour in D changed at some point, so if you see examples/code that don't
work, it is just too old.
version (foo) {
extern(something):
}
will only be applied to that version block, and so it won't apply to the
symbols following below the version blocks. Either duplicate all symbols in
each version block, or use
extern (System):
symbols ...
System will then put in the correct extern depending on platform.

Thanks Lars, extern (System): works just fine :)
