<!-- ##### MACRO GLIB_MAJOR_VERSION ##### -->
<para>
The major version number of the GLib library.
Like #glib_major_version, but from the headers used at
application compile time, rather than from the library linked against
at application run time.
</para>


<!-- ##### MACRO GLIB_MINOR_VERSION ##### -->
<para>
The minor version number of the GLib library.
Like #gtk_minor_version, but from the headers used at
application compile time, rather than from the library linked against
at application run time.
</para>


<!-- ##### MACRO GLIB_MICRO_VERSION ##### -->
<para>
The micro version number of the GLib library.
Like #gtk_micro_version, but from the headers used at
application compile time, rather than from the library linked against
at application run time.
</para>


<!-- ##### MACRO GLIB_CHECK_VERSION ##### -->
<para>
Checks the version of the GLib library.
Returns %TRUE if the version of the GLib header files is the same 
as or newer than the passed-in version.
