[Haifux] Intermingled code and declarations and gcc

[Orna Agmon Ben-Yehuda]

Hi Eli,

Is this C? You are defining an array with an unknown length at compile
time. It won't work anyhow, no matter what the value of the length var
is. You need a malloc there.

Unless this is C++ with some overriding?

Orna.
