Fixed RUBY_RM_RECURSIVE when autoconf met the required version

2020-12-12T16:16:57+00:00

Before 9189cf5793cd527a86b711d15d5fd0633ec082e1 the result of
`m4_version_compare` was compared to -1, however the `$2` of
`m4_version_prereq` has different meaning and is expanded when
the required version met.

Revert "Moved aclocal.m4 to macro directory"

2020-04-05T02:53:07+00:00

This reverts commit 4a6571dbc14ee4e88c12cd9931f7695077a3ee6e,
because chkbuild does not follow.

Moved aclocal.m4 to macro directory

do not assume GCC for __builtin_setjmp

2020-02-06T02:46:51+00:00

Namely recent Sun C compiler has this function, and is not a GCC.
Meanwhile the code without RUBY_JMP_BUF assumes GCC.  We have to define
the macro when we detect __builtin_setjmp for non-GCC compilers.

typedef rb_jmpbuf_t to void *[5] if __builtin_setjmp is used

2019-09-21T04:24:58+00:00

The built-in version operates on a buffer of 5 words, much smaller than
the size of jmp_buf defined in libc.
Note, powerpc requires 5 words, while arm and x86_64 just require 3.

Remove IA64 support.
