-In the XSI standard and SVr4 manual pages, many entry points have prototype
-arguments of the for \fBchar *const\fR (or \fBcchar_t *const\fR, or
-\fBwchar_t *const\fR, or \fBvoid *const\fR). Depending on one's interpretation of the
-ANSI C standard (see section 3.5.4.1), these declarations are either (a)
-meaningless, or (b) meaningless and illegal. The declaration
-\fBconst char *x\fR is a modifiable pointer to unmodifiable data, but
-\fBchar *const x\fR' is
-an unmodifiable pointer to modifiable data. Given that C passes arguments by
-value, \fB<type> *const\fR as a formal type is at best dubious. Some compilers
-choke on the prototypes. Therefore, in this implementation, they have been
-changed to \fBconst <type> *\fR globally.
