"""This script reads config.h.meson, looks for header
checks and writes the corresponding meson declaration.
Copy config.h.in to config.h.meson, replace #undef
with #mesondefine and run this. We can't do this automatically
because some configure scripts have #undef statements
that are unrelated to configure checks.
