Beware - some prototypes are left out of headers because various
systems have conflicting definitions of them.  xmalloc, for example,
is defined different ways in different GNU packages, and none expect
the system headers to have them.

If the #define is after the prototype, the prototype never gets used.
If it's before the prototype, the prototype causes a syntax error.
Why not just include the #define and skip the prototype?
