AC_PREREQ([2.57])

dnl
dnl Version should match the current XComposite version. XCompositeQueryVersion
dnl returns the version from xcompositewire.h, NOT the version we set here.
dnl But we try to keep these the same.  Note that the library has an extra
dnl digit in the version number to track changes which don't affect the
dnl protocol, so Xcomposite version l.n.m corresponds to protocol version l.n
dnl that 'revision' number appears in Xcomposite.h and has to be manually
dnl synchronized.
