5dd941b311 Fix modulo by zero 
Yet another case caught by scan-build:

src/link/patch.c:188:21: warning: Division by zero
                        value = popRPN() % value;
                                ~~~~~~~~~^~~~~~~

Just copy over the code from the division case, with a few modifications.

Fix possible null pointer dereference

5863cd10b8 Fix possible null pointer dereference 
It's possible that if the FILE passed to yy_create_buffer is at the
end-of file, there may be a null pointer dereference.

This should hopefully fix that.

Found with clang-tools' scan-build:

src/asm/lexer.c:281:25: warning: Array access (via field 'pBuffer')
 results in a null pointer dereference
        pBuffer->pBuffer[size] = 0;
                 ~~~~~~~       ^
1 warning generated.

1e3ce2a36f Use more conventional permissions and man-page directory 
As 444 and 555 seem to be used for no apparent reason, use the more
conventional 644 and 755.

/man is typically unused or a symlink to /share/man now, so just use
/share/man.

7eb73d766e Make compilation optimized unless debugging 
Note: I wanted to enable `-Og` on `develop`, but this generated warnings
(thus, errors) that aren't in `-O0`. Needs further investigation, but
annoyingly some of those are within `extern/` code, thus requiring
different flags, which AFAIK is only possible (sanely) with GNU Make.

db1eb8fbcb Revert "Prevent RGBASM from outputting corrupted files" 
This reverts commit 06fe27c516.

According to Microsoft's documentation
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/tmpfile?view=vs-2019
`tmpfile` attempts to create the temporary file at the **root** folder
This seems to assume that the user has admin rights; might be a compat
thing, idk, but it breaks on people's computers.
(CI didn't catch it, annoyingly.)

Reverting to make RGBASM usable on most Windows computers.
(Sanely-configured ones, at least.)
Another solution to #446 needs to be figured out, yay...
