They return the checking argument without modification, so the values
are already there. Maybe we should change the return type to `void` but
keep them unchanged for compatibility.

Consistent number conversion function names:
* `mrb_value` to immediate (C) value
* `mrb_int()` -> `mrb_as_int()`
* `mrb_to_flo()` -> `mrb_as_float()`
* `mrb_value` to `mrb_value` (converted)
* `mrb_to_int()'
* `mrb_Integer()` - removed
* `mrb_Float()` -> `mrb_to_float`
Consistent function name (avoid `_flo` suffix):
* `mrb_div_flo()` -> `mrb_div_float`

This reverts commit dc51d89ac22acc60b9bfeed87115863565b74085.
|
|
Instead of including `mruby/presym.h` everywhere, we provided the
fallback `mruby/presym.inc` under `include/mruby` directory, and specify
`-I<build-dir>/include` before `-I<top-dir>/include` in `presym.rake`.
So even when someone drops `-I<build-dir>/include` in compiler options,
it just compiles without failure.
|
|
Addressed an issue where existing programs linking `libmruby.a` could only
be built by adding `<build-dir>/include` to compiler's include path.

The "a"/"*" specifier of the `mrb_get_args()` function will now return `const mrb_value *`.
This is because it is difficult for the caller to check if it is an array object and write-barrier if necessary.
And it requires calling `mrb_ary_modify()` on the unmodified array object, which is also difficult (this is similar to #5087).

Where fixnum overflow can happen.

- `MRB_WITHOUT_FLOAT` => `MRB_NO_FLOAT`
- `MRB_USE_FLOAT` => `MRB_USE_FLOAT32`
The former is to use `USE_XXX` naming convention. The latter is to make
sure `float` is 32bit float and not floating point number in general.
|

- The `s` specifier is a string pointer obtained without performing `mrb_str_modify()`, so it cannot be changed.
- The `z` specifier cannot be changed because it is a string pointer obtained by `RSTRING_CSTR()` which returns `const char *`.

Adding MRB_MINGW32_LEGACY in common.h in order to identify the legacy MinGW environment (i.e. NOT to be confused with MinGW-w64).
For more info about MinGW defined macros, see: https://sourceforge.net/p/predef/wiki/Compilers/

It is described as `struct __stat32` in the MSVC reference manual.
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/stat-functions?view=vs-2019
But it doesn't really exist, so it must use `struct _stat32`.
It also replaces `struct __stat64` with `struct _stat64` to make it look
nicer.

`mrb_get_arg1()` raises `ArgumentError` if the method does not receive one
argument.
And replaces all `mrb_get_args(mrb, "o", &arg)` by the new function.

`mrb_string_value_cstr` and `mrb_string_value_len`: obsolete
`mrb_string_cstr`: new function to retrieve NULL terminated C string

The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in
my environment than before the introduction of new specifiers/modifiers
(5116789a) with this change.

BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613,
so I put it back.

Because it always allocate new string. Replace with the followings:
- Use `RSRING_PTR` if string is guaranteed to be null-terminated.
- Use `mrb_string_value_cstr` or `mrb_get_args("z")` if return value isn't
modified.

We have added internal convenience method `__to_str` which
does string type check.
The issue #3854 was fixed but fundamental flaw of lack of stack
depth check along with fibers still remains. Use `MRB_GC_FIXED_ARENA`
for workaround.
