What runs before main()?
<p>After testing on msvc8, I found:</p>

<ol>
<li>Parse GetCommandLine() to argc and argv</li>
<li>Standard C Library initialization</li>
<li>C++ Constructor of global variables</li>
</ol>

<p>These three things are called before entering main().</p>

<p>My questions are:</p>

<ol>
<li>Will this execution order be different when I porting my program to different compiler (gcc or armcc), or different platform?</li>
<li>What stuff does Standard C Library initialization do? So far I know setlocale() is a must.</li>
<li>Is it safe to call standard C functions inside C++ constructor of global variables?</li>
</ol>
