You could also use the @samp{-D} option to GCC, but it's better if you make the source files indicate their own meaning in a self-contained way. +This system exists to allow the library to conform to multiple standards. +Although the different standards are often described as supersets of each +other, they are usually incompatible because larger standards require +functions with names that smaller ones reserve to the user program. This +is not mere pedantry --- it has been a problem in practice. For instance, +some non-GNU programs define functions named @code{getline} that have +nothing to do with this library's @code{getline}. They would not be +compilable if all features were enabled indescriminantly. + +This should not be used to verify that a program conforms to a limited +standard.
