Bug #1236: RUBY_VERSION not defined
http://redmine.ruby-lang.org/issues/show/1236

Author: Charlie Savage
Status: Open, Priority: High
Category: core, Target version: 1.9.1
ruby -v: ruby 1.9.2dev (2009-03-01) [i386-mswin32_90]

Building from trunk with MSVC 2008.

ruby/config.h is generated with this line:

#define RUBY_LIB_VERSION STRINGIZE(RUBY_VERSION_MAJOR)"."STRINGIZE(RUBY_VERSION_MINOR)"."STRINGIZE(RUBY_VERSION_TEENY)

But RUBY_VERSION_MAJOR, RUBY_VERSION_MINOR, RUBY_VERSION_TEENY are not defined in this file or in any file that is installed.  They are defined in trunk/version.h but that is not installed.

Nor is RUBY_VERSION defined. 

This is an issue because libxml-ruby uses st.h, and thus needs code that looks like this:

#if RUBY_VERSION < "1.9.0"
#include <st.h>
#else
#include <ruby/st.h>
#endif

Right now that doesn't work because RUBY_VERSION is not defined.
