# 1. Compile a project with g++-3.3 while the imported project was configured
# using the 'c++' alias (which at the time meant g++-3.3)
# 2. This variable also becomes handy when the project your are importing has been
# compiled with a compiler you do not have access to, but offer a compatible ABI with
# yours.
# WARNING: Do not use this variable with C++ compiler with incompatible ABI
