Fix 1998/schnitzi for linux

It segfaulted due to wrong type of a variable.

It still crashes under macOS which I will be looking at in the near
future but it at least works for linux.

I noted in the bugs.md a compiler warning that should not be changed as
it's not a bug and in fact 'fixing' it will introduce a bug.

-    In literary circles, there is a poetic form called a "lipogram",
-    which is a poem in which a specific letter has been distinctly
-    avoided.  This principle can be applied in other ways.  For
-    instance, in this paragraph, the vowel which immediately follows
-    't' in the alphabet is nowhere to be seen.  There is even an
-    entire novel (E. V. Wright's "Gadsby") in which no word contains
-    the letter 'e'.

-    The IOCCC has been no stranger to this concept.  Several winning
-    entries from years past have accomplished interesting feats while
-    completely avoiding the use of certain C constructs thought to
-    be essential (e.g. 1988's robison.c).  If you have to ask why they
-    would do it this way, then this contest just isn't for you.

-    In continuing with this fine tradition, this program suggests to
-    the ANSI committee some new practical simplifications for the C
-    language.  For instance, it appears that CONDITIONAL BRANCHING isn't
-    really necessary.  So, we can do away with while, do...while, for,
-    if/else, switch, ?:, or anything else that might cause any kind of
-    nondeterministic jump in the code.  There's too much uncertainty
-    in the world anyway.

-    Function parameters and return types just confuse people anyway, so
-    get rid of them.  Same with local variables.  In fact, all you really
-    need are assignment statements, and maybe one printf() and one goto.

-    memory capacity, since the function call stack never goes beyond
-    a depth of one.
