# FIXME: This does not do full C prototype parsing, but relies on
# knowledge on how the X11 include files are formatted. It will
# probably need to be modified for new include files. It also fails
# for certain prototypes (notably those with function pointer
# arguments or results), so these must be added manually. And it
# relies on a fixed location of X11 includes (/usr/X11R6/include/).
