You should drop that line - those comments are used for us to figure out which
xproto version to list in the pkg-config requirements when using newer _X_* 
macros out of Xfuncproto.h, so doesn't make sense here.

Also be warned that using a macro name starting with an _ will cause you to get
complaints about violating the "reserved for the implementation" rule in the
ANSI/ISO C standards from people who consider the implementation to solely be
the compiler, not the OS.  https://bugs.freedesktop.org/show_bug.cgi?id=70686
for example.
