There are lots of people who are still using old compilers. VC6/VC7 and
even really old GCC versions, like 2.95.x. For example, my university
has GCC 3.1. It might be true that there are compilers available that
can compile your code on 90% of all computer platforms. However, I doubt
that 90% of all C++ developers can use those compilers in their daily
