+<h1> The <tt>skalibs/gccattributes.h</tt> header </h1>
+
+<p>
+ <tt>skalibs/gccattributes.h</tt> is a set of wrappers around
+<a href="http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html">gcc
+attributes</a> (duh). It defines macros that are always valid, and
+that have no effect if the compiler is not gcc or the used version
+of gcc does not support the wanted attribute.
+</p>
+
+<p>
+ For instance:
+</p>
+
+<pre>
+ extern unsigned int str_len (char const *) gccattr_pure ;
+</pre>
+
+<p>
+ defines the <tt>str_len</tt> function as <em>pure</em> if it is
+supported.
+</p>
+
+<p>
+ The source code is self-explanatory.
