It takes longer to insert the e-mail address for this note using Microsoft
Outlook Express, than it does to compile a package body with Aonix Object
Ada under Windows 98. The slowest part of Object Ada is the Microsoft
linker. The problems with Ada compilation speed and CPU requirements are now
ancient history. Any computer than permits the reasonable use of Microsoft
Office is sufficient for Ada software development. In fact, the situation is
now reversed. The compiler manufactures can now afford to reduce the
compilation speed in the case of providing a significant benefit, such as
execution efficiency or improved error messages.
