/* forward function declarations */
Add more prototypes in mach/proto/as Change "register i;" to "int i;" to so clang stops warning about implicit int. Use function prototypes so clang stops warning about implicitly declared functions.

/* comm2.y */
Use libc assert(); fix dependencies; unbreak isduo(). Switch from custom assert() to libc assert() in mach/proto/as. Continue to disable asserts if DEBUG == 0. This change found a problem in the build system; comm2.y was missing depedencies on comm0.h and comm1.h. Add the missing dependencies to the cppfile rule. Allow the dependencies by modifying cppfile in first/build.lua to act like cfile if t.dir is false. Now that comm2.y gets rebuilt, I must fix the wrong prototype of yyparse() in comm1.h. I got unlucky as induo() in comm5.c was reading beyond the end of the array. It found an operator "= " ('=' then space) in the garbage, so it returned a garbage token number, and "VAR = 123" became a syntax error. Unbreak induo() by terminating the array.

Cut down some clang warnings Edit C code to reduce warnings from clang. Most warnings are for implicit declarations of functions, but some warnings want me to add parentheses or curly braces, or to cast arguments for printf(). Make a few other changes, like declaring float_cst() in h/con_float to be static, and using C99 bool in ego/ra/makeitems.c and ego/share/makecldef.c. Such changes don't silence warnings; I make such changes while I silence warnings in the same file. In float_cst(), rename parameter `str` to `float_str`, so it doesn't share a name with the global variable `str`. Remove `const` from `newmodule(const char *)` in mach/proto/as to silence a warning. I wrongly added the `const` in d347207. For warnings about implicit declarations of functions, the fix is to declare the function before calling it. For example, my OpenBSD system needs <sys/wait.h> to declare wait(). In util/int, add "whatever.h" to declare more functions. Remove old declarations from "mem.h", to prefer the newer declarations of the same functions in "data.h" and "stack.h".

Add .data8 for 8-byte literal integers to the assembler. This takes literal integers, not expressions, because each machine defines its own valu_t for expressions, but valu_t can be too narrow for an 8-byte integer, and I don't want to change all the machines to use a wider valu_t. Instead, change how the assembler parses literal integers. Remove the NUMBER token and add a NUMBER8 token for an int64_t. The new .data8 pseudo emits all 8 bytes of the int64_t; expressions narrow the int64_t to a valu_t. Don't add any checks for integer overflow; expressions and .data* pseudos continue to ignore overflow when a number is too wide. This commit requires int64_t and uint64_t in the C compiler to build the assembler. The ACK's own C compiler doesn't have these. For the assembler's temporary file, add NUMBER4 to store 4-byte integers. NUMBER4 acts like NUMBER[0-3] and only stores a non-negative integer. Each negative integer now takes 8 bytes (up from 4) in the temporary file. Move the `\fI` and `\fP` in the uni_ass(6) manual, so the square brackets in `thing [, thing]*` are not italic. This looks nicer in my terminal, where italic text is underlined.
