cc59730c5b Cleanup the RPN evaluator somewhat 
Make the bool field an actual bool

comments)

0a04904b75 Refactor RPN binary expressions into a single func

af6f62701c Remove ambiguous charmap syntax 
The syntax was `charmap "anything", "string"`; the second string was
already handled by `const`, but to the same effect... the ambiguous
declaration has been removed, leaving us at "only" two reduce/reduce
conflicts.

ed72baca2a Make more symbol functions const 
Can't hurt to specify those as they are now. Perhaps it'll enable slightly more
compiler optimizations, too?

93ee417567 Fix timestamp symbols on Windows (partially) 
Windows does not honor `%F` nor `%T` in `strftime`. These are worked around
by writing the full format they serve as a short for.
However, Windows also treats `%z` and `%Z` identically, where SUS instead
requires `%z` to output a ±XXXX offset.
Since the current information is broken (no information), this isn't *breaking*
anything, but at least provides something a human will probably understand.
`__ISO_8601_UTC__` is unaffected because it hardcodes the timezone character,
only `__ISO_8601_LOCAL__` suffers from this.

a9cb4f8245 Make RGBASM overwrite output files atomically 
Fixes rednex/#446.
I am not sure this is the best (in cases where the target directory
is not writable but the target file is), but maybe this can be
toggled via a flag, for example.

12f2f654dd Add -MG 
This option allows for automatic dependency detection and generation:
as soon as a missing file is found, it is output to the dep file, and
assembly immediately aborts. (No .o file is produced, even if `-o` was
speicified.) This doesn't cause an error, either; the point is that once
the file is added to the dep file, the Makefile is re-parsed, and this
time the file will be generated, so the dep list builds up automatically.
This mimicks GCC's option and behavior.

0649b360fb Allow specifying multiple dependency targets 
This is done to match GCC's behavior.
Also, this unifies the code of -MT and -MQ.

f1f314270d Add -MQ 
Just like GCC's -MQ, this is basically -MT but the file name is escaped.
