 Problem:

 Plugin authors cannot reliably use $wp_version when doing their own
 feature development without hitting a chicken-egg scenario.

 Example:

 I want a plugin to call function foo_32() for all major WordPress 3.2
 branch versions.
 I want a plugin to call function foo_33() for all major WordPress 3.3
 branch versions.

 version_compare() is inadequate for this when used in conjunction with
 WordPress core's versioning scheme:

 3.2.1 is greater than 3.2
 3.3-RC2 is less than 3.3

 Paradox:

 version_compare( '3.2', $wp_version ); -- Fails when 3.2.1 comes out
 version_compare( '3.3', $wp_version ); -- Fails before 3.3 is released

 Using version_compare() with any combination of operators yields the same
 result.

 Proposed Solution:

 A new global: $wp_major_version

 This would get bumped in trunk when development starts on the next major
 version. It provides plugin and theme authors the luxury of not needing to
 parse the major version out of $wp_version themselves. Patch attached.
