@ -19,6 +19,20 @@ comments. 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. It is insufficent for this purpose, as it will not protect you
from including header files outside the standard, or relying on semantics
undefined within the standard.
