Use C89 size_t for sizes from sizeof() or to malloc() or realloc().
Remove obsolete (unsigned) casts. Sizes were unsigned int in
traditional C but are size_t in C89.
Silence some clang warnings. Add the second pair of round brackets in
`while ((ff = ff->ff_next))` to silence -Wparentheses. Change
`if (nc_first(...))/*nothing*/;` to `(void)nc_first(...);` to silence
-Wempty-body. The code in compute.c nc_first() had the form
`if (x) if (y) s; else t;`. The old indentation (before 10717cc)
suggests that the "else" belongs to the 2nd "if", so add braces like
`if (x) { if (y) s; else t; }` to silence -Wdangling-else.
Shuffle extern function declarations. Add missing declaration for
LLparse(). Stop declaring RENAME(); it doesn't exist. Move some
declarations from main.c to extern.h, so the C compiler may check that
the declarations are compatible with the function definitions.
Assume that standard C89 remove() is available and doesn't need the
UNLINK() wrapper.
In lib/incl, don't need to include <stdio.h> nor <stdlib.h> to use
assert().
Remove alloc.h. If you don't clean your build, then an outdated
BUILDDIR/obj/util/LLgen/headers/alloc.h will survive but should not
cause harm, because nothing includes it. Don't need to remove alloc.h
from util/LLgen/distr.sh, because it isn't there.
Run the bootstrap to rebuild LLgen.c, Lpars.c, tokens.c.
