This lets us use libcapstone directly from miniruby so we don't need a
Ruby Gem to to dev work.
Example usage:
```ruby
def foo(x)
if x < 1
"wow"
else
"neat"
end
end
iseq = RubyVM::InstructionSequence.of(method(:foo))
puts UJIT.disasm(iseq)
100.times { foo 1 }
puts UJIT.disasm(iseq)
```
Then in the terminal
```
$ ./miniruby test.rb
== disasm: #<ISeq:foo@test.rb:1 (1,0)-(7,3)> (catch: FALSE)
local table (size: 1, argc: 1 [opts: 0, rest: -1, post: 0, block: -1, kw: -1@-1, kwrest: -1])

As we do not use config.h.in, just define the helper macro
instead.
|
|
Although `AC_PROG_CC_C99` has been obsolete, `AC_PROG_CC` is not
and the latter is necessary not to make C++ compiler mandatory.

This allows easy differentiation between ABI incompatible platforms like MSWIN64 and MSVCRT-based MINGW32.
This also implicates a distinct rubygem platform which is also "x64-mingw-ucrt".
Although the term "mingw32" is the OS-part for 64 bit systems as well, the "32" is misleading and confusing for many users.
Therefore the new platform string drops the "32" from the OS part to just "mingw".
This conforms to the common practice of windows platform testing per RUBY_PLATFORM=~/mswin|mingw/ .

Pattern matching for target_os in configure script should be permissive if we consider suffixing something onto "mingw32".

Actually disabled at 181a3a2af5df88d145b73a060d51fe437c8c4ad4 in
2004, it has remained in config.status and been carried over to
rbconfig.rb.

Expand variables undefined in configure.ac, RUBY_RELEASE_DATE and
so on.
|

So that it is no longer needed in ruby.pc.in.

It is reported that combination of `--enable-shared --with-jemalloc`
breaks on Debian bullseye (testig). Deeper investigation revealed that
this system's `ld(1)` is patched, to turn `ld --as-needed` on by
default.
This linker flag strips "unnecessary" library dependencies from an
executable. In case of `ruby(1)` (of `--enable-shared`), because
everything is in `libruby.so`, the binary itself doesn't include any
calls to `malloc(3)` at all. So in spite of our explicit `-ljemalloc`
flag, it is ignored. Libc's one is chosen instead.
This is not what we want. Let's force our `ruby(1)` link what we want.

* honor actually used headers
* include sys/user.h only when `PAGE_SIZE` is not defined
|
|
On darwin we avoid including sys/user.h to avoid a conflict. Previously
we still ended up with PAGE_SIZE being defined because the headers for
system malloc define it. However, when compiling with jemalloc nothing
would define PAGE_SIZE.
This commit changes configure.ac so that we never use the PAGE_SIZE
constant on darwin and to always use the sysconf fallback.

This function should be always available, as POSIX-compliant or
Windows platform are required since 1.9. Also the code in this

LIST_HEAD in ccan/list conflicts with sys/queue.h.
```
./ccan/list/list.h:75:9: warning: 'LIST_HEAD' macro redefined [-Wmacro-redefined]
^
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/sys/queue.h:465:9: note: previous definition is here
^
```
|
|
The current fix for PAGE_SIZE macro detection in autoconf does not work
correctly. I see the following output with running configure on Linux:
```
checking PAGE_SIZE is defined... no
```
Linux has PAGE_SIZE macro. This is happening because the macro exists in
sys/user.h and not in the malloc headers.
Notes:
Merged: https://github.com/ruby/ruby/pull/4461
|
|
As PAGE_SIZE may not be a preprocessor constant, dispatch at
runtime in that case.

include/ruby/internal/has/builtin.h uses HAVE_BUILTIN___BUILTIN_EXPECT
for icc but previously it was not defined.
This is a follow up of 8b32de2ec9b72d4c9ede19b70ec9497718fb25a6 and this

`AC_COMPILE_IFELSE` does not know which is the cause of the
