These files were taken verbatim from the GNU C Library.
This directory contains source for functions which are occasionally
missing from popular Unix variants. These functions will *not* be
used if your system includes support for them already, with the
following exceptions:
* xmalloc(), xstrdup(), xstrtol() and xstrtoul(), since these
are not standard functions.
* Any functions you explicitly request to be used. This is
useful when a function on your system is known to be buggy -
for instance, old releases of Solaris are known to have a
buggy alloca(). In general, you can count on autoconf to
do a good job figuring out whether you need these routines.
However, if you want to outsmart autoconf, merely edit the
`config.h' in the main distribution directory.
In general, you shouldn't have to worry about these details -- just
let autoconf take care of everything.
