title: Migrating from Rational Apex Ada compiler to GCC Ada compiler
body: <p>I will be working on a software development project using Ada language. Customer is using Rational Apex Ada compiler and I will be using GNU compiler. My code should work fine in customer's pc. What are all the possible compiler dependent code in Ada language? So that I can develope a compiler independent code. Also I want to compile and execute customer's code in my pc.</p>
  
  <p>Thanks
