uemacs is not a subprogram and doesn't seem it will be, so there is no reason
to leave this macro. And this macro is defined to 0, so we never reach the path
where we test for this macro.

Return statement is not a function so remove superfluous use of parenthesis.

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.
