internal.h: unify our own stdtbool.h implementation because we had another one in missing/stdbool.h as well. Assuming that _Bool does not exist when stdbool.h is absent, I'm in favor of r57462 implementation rather than r61326. Note that Visual Studio 2013 has stdbool.h and thus r57462's commit message is somewhat misleading. This missing/stdbool.h is for Visual Studio 2012 or older, and for Oracle Solaris Studio 12.2 or older because it's added in 12.3 https://docs.oracle.com/cd/E24457_01/html/E21987/gkeza.html. missing/stdbool.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66739 b2dd03c8-39d4-4d8f-98ff-823fe69b080e 2019-01-06 09:53:43 -05:00			`#ifndef __bool_true_false_are_defined`
