Lets welcome uEmacs/PK to the year 2010! As expected, the patch has no effect
on the generated code:

Most of them were harmless: gcc not being smart enough to realize that
an uninitialized variable was never used if it wasn't initialized etc.
Some of them were name clashes ("crypt()" is a standard library
function, so rename it to "myencrypt()") etc.

make sure to include <errno.h>, and allow for the fact that newer
gcc's don't allow function declarations in function scope (don't
ask me why, but there you have it..)
This is a slightly updated version of uemacs-PK (PK is Pekka
Kutvonen) which was used at Helsinki University a long time
ago. My fingers cannot be retrained.
