a bit less messy.

* a check that the library in use is compatible with

* Compatibility is defined by two things: first the version
* of the running library is newer than the version

* the running library must be binary compatible with the
* version @required_major.required_minor.@required_micro
* (same major version.)
*
* This function is primarily for GTK modules; the module
* can call this function to check that it wasnt loaded
* into an incompatible version of GTK. However, such a
* check isnt completely reliable, since the module may be
* linked against an old version of GTK and calling the
* old version of gtk_check_version(), but still get loaded
* into an application using a newer version of GTK.
