This fails to build if lang/gcc/8 is installed because it picks up the
old ansidecl.h which misses a few #defines.
One option is to define the missing ones away. Defining them to the
right thing is harder since they are passed through several shells, so
getting the quoting right is tricky.
Hopefully someone else has a better idea.
